Our hearts are deceitful, but God knows our hearts inside out. He has made our hearts new. The labyrinth belongs to him now and he is gradually remodelling it into a beautiful place where sin cannot hide.  And if you want to know the true state of your heart, the Lord will help you. Ps 139.23f: Search me, O God, and know my heart! Try me and know my thoughts! 24And see if there be any grievous way in me, and lead me in the way everlasting!

In Proverbs 4.23 Solomon warns his son, ‘Keep your heart with all vigilance, for from it flow the springs of life.’ He goes on to give admonitions about the mouth, the eyes and the feet (vv24-27), but it is the heart that must be guarded above all else. Why?
In Scripture, the word ‘heart’ is used more than 1000 times, but it almost never refers to the physical organ inside our chests. The Theological Wordbook of the Old Testament sums up all the usages of the term in this way: it is ‘the richest, most all-encompassing biblical term for the totality of a man’s inner nature.’ The heart is said to do a wide range of things in the Bible, but all its many activities fall into one of the three main faculties of the soul: the mind, the affections and the will. It includes the mind—our thoughts, imagination, fantasies, judgments and attitudes. It encompasses the affections—our emotions, our desires and longings, our revulsions. And it describes the will—our choices, decisions and motivations.
Once we understand that the heart involves all these things, it becomes even clearer why we must guard it with all vigilance, before all else—because it is so fundamental. It is the control centre of the whole person. Indeed Scripture sometimes uses ‘heart’ as a kind of synonym for the self (e.g. Gen 18.5; Ex 9.14; 1Pt 3.4: ‘…the hidden person of the heart’.)
We also need to guard our hearts with all vigilance because they are under constant attack. From the world and the devil outside ourselves of course, but also—most dangerously of all—from an enemy within: the flesh—a traitor inside our own hearts, a Judas looking for an opportune moment to hand us over to sin. The heart is deceitful above all things, and desperately sick; who can understand it? (Jer 17.9). It is like an unsearchable labyrinth, with endless twists and turns, blind alleys and dark corners where the Minotaur of our indwelling sin lurks in wait for us.
We need to guard our hearts too because the Lord wants our hearts. Prov 23.6: My son, give me your heart. What a beautiful and powerful incentive this is! We are keeping our hearts for our Father! We wouldn’t be satisfied with a marriage where our spouse was dutiful and faithful outwardly, but longed inwardly to be with someone else to whom their heart belonged. Why would God be content with that from us? He wants our hearts—our minds, our affections and our wills. The totality of our inner nature and not just our outward behaviour. Isa 29.13: And the Lord said: “…this people draw near with their mouth and honor me with their lips, while their hearts are far from me… Ps 51.16f: For you will not delight in sacrifice, or I would give it; you will not be pleased with a burnt offering. The sacrifices of God are a broken spirit; a broken and contrite heart, O God, you will not despise.
How then do we do this vital work of guarding our hearts? The first step is to do a ‘spiritual MRI scan’ of our hearts. We need to know the current state of our hearts so that we can address the problems and weaknesses we find. Rom 12.3 tells us to ‘think [of ourselves] with sober judgment.’ The Puritan John Flavel, in an exposition of Prov 4.23, wrote these challenging words: ‘Some people have lived forty or fifty years and have had scarcely one hour’s discourse with their own hearts! … Of all works in religion, this is the most difficult, constant and important work. Heart work is indeed hard work. To shuffle over religious duties with a loose and heedless spirit will cost no great pains. But to set yourself before the Lord and tie up your loose and vain thoughts to a constant and serious attention upon him, this will cost you something.’ John Owen in his book The Mortification of Sin advises his readers: “Be acquainted, then, with thine own heart: though it be deep, search it; though it be dark, inquire into it; though it give all its distempers other names than what are their due, believe it not.”
As we carry out this spiritual MRI scan of our hearts we need to bear in mind what the heart is—the totality of our inner nature: the mind, will and affections. We need to assess all three areas of the heart with probing diagnostic questions. Here are some examples of what that might look like:
A. The mind (thoughts, attitudes, imagination, plans, judgments, discernment).
a) What do you think about? Do you think about spiritual things? The glory of God? The Person and work of Jesus Christ? The Gospel of grace? Sinclair Ferguson once asked the unsettling question, ‘How many Christians today could sit in a room without any resources and think about Jesus Christ for more than five minutes before they run dry?’
b) What do you think about when you’re not focused on specific tasks? John Owen calls these ‘Natural, voluntary thoughts’. They’re like the screensaver that comes up on our computer screens. When the computer is idling for more than a few minutes, it’s the image that appears. What images appear in your mind when it’s not actively engaged in a particular task? Owen says, ‘These thoughts give the best measure of the frame of our minds and hearts… such as the mind of its own accord is apt for, inclines & ordinarily betakes itself unto.’ In other words, do you think about spiritual things when you’re not forced to because you’re listening to a sermon in church or taking part in a Bible study?
c) Owen also asks, do you abound in spiritual thoughts? What proportion of your thoughts are spiritual compared to your thoughts about other things? Here’s a very challenging way of asking the question: do spiritual thoughts ever distract you when you’re engaged in other pursuits? We all know what it’s like to be distracted by earthly thoughts intruding when we’re trying to pray or read the Bible in our daily devotions or listen to a sermon, but is it ever the other way around? Do you ever find yourself thinking about the Lord Jesus when you’re in the middle of watching a film or a football match?

Jesus there on the cross felt in His human soul a disruption of His fellowship with God. The disruption was real, and the agony which Jesus experienced as a result of it in His totally pure and uncalloused human soul is beyond our ability to comprehend. In His question from the cross, Jesus was talking about His experiencing through His human nature the wrath of God against sin.
We are today going to consider the middle of the seven sayings of the cross. The fourth word from the cross is “My God, My God, why have You forsaken Me?” Of all the seven, this is both the most mysterious and the most revealing. Of all the seven, it is the clearest expression of the suffering which Jesus experienced in our place as the payment for our sins. Yet of all the seven, it is also the most difficult for us to understand. Thinking about this cry of abandonment reminds us that God’s ways are past our finding out. We can know God, but we can never fully comprehend Him with our creaturely minds. As we come to the essence of our Lord’s atoning suffering, even Jesus in His humanity cries out “why.” Jesus in His divinity understands all mysteries, but Jesus in His humanity on this occasion cried out, “why.”
As we consider today’s text, we will be approaching the limits of what we can understand. We must prayerfully seek to understand more and more of God’s truth. Yet we must also be prepared to acknowledge in humility when we have reached those truths which are beyond even the grasp of an angel’s mind.
In order to provide some context for the fourth saying, I want to look today also at two other sayings, the second and the sixth. The second saying from the cross, found in the gospel according to Luke, is “Assuredly, I say to you, today you will be with Me in Paradise” (Luke 23:43). The fourth statement is in our text for today in the gospel according to Mark. It is, “My God, My God, why have You forsaken Me?” The sixth statement is found in the gospel according to John. It is, “It is finished” (John 19:30).
We will look at these three sayings from the cross under the headings, Confidence, the Cry and Completion.
We will now consider the second saying from the cross under the heading Confidence. Jesus has been officially condemned as guilty by the Roman governor Pilate, even though Pilate also unofficially admitted that Jesus had done nothing worthy of death and was an innocent man. In God’s providence, that course of events fit perfectly with the spiritual reality. Jesus was indeed innocent of any crime, even sinless of any sin. Yet He was legally condemned for sins, not sins that He had committed, but our sins for which He voluntarily took responsibility. The Roman soldiers carried out the Roman sentence that resulted from the Roman condemnation. They nailed Jesus to a wooden cross, a tree of sorts. This also fit perfectly with the spiritual reality. According to the law of Moses, being hung on a tree is a sign of God’s curse. And Jesus was under God’s curse so that all who believe in Him might receive God’s blessing. So here we have Jesus condemned and cursed. Yet the second saying from the cross reveals to us that Jesus was optimistic even in these circumstances. He was optimistic because He was living by faith, faith in God’s revealed will, faith in the message of the Bible. That is why the writer to the Hebrews wrote in chapter twelve of his inspired letter that Jesus, for the joy that was set before Him, endured the cross, despising the shame. What joy? The joy of obeying His Heavenly Father. The joy of doing that work which was necessary for the salvation of those sinners whom the Father had sent Jesus to save. The joy of the anticipated exaltation with which Jesus knew that the Father would exalt Him after His work of humiliation was completed. Jesus had all these assurances because Jesus knew the Old Testament, the extent of the Scriptures in His day.
When the resurrected Jesus appeared to His twelve disciples in a closed room on the evening of the Sunday when Jesus rose from the dead, Jesus explained to them the Old Testament predictions of Jesus’ suffering, death and resurrection.
And He opened their understanding, that they might comprehend the Scriptures. Then He said to them, “Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day…Luke 24:45-46
This message of Scripture is the basis for the confidence that Jesus had when He said to the believing thief on the cross: “Assuredly, I say to you, today you will be with Me in Paradise.” Speaking from the place of condemnation and curse, Jesus said with confidence that He would be in Paradise later that very day. Paradise is here a reference to heaven, the location of the New Jerusalem, that celestial holding place where the spirits of departed saints go to await the coming day of bodily resurrection. Jesus was not resurrected from the dead until Sunday, the third day after His death, but on Friday, the very day of His physical death, Jesus’ human spirit went to be with His Father in heaven. Jesus also spoke with confidence that the believing thief on the cross would also go to heaven that very day. Jesus died first, and Jesus’ human spirit was in heaven to greet the soul of the believing thief upon his arrival. Jesus knew when He spoke to the believing thief that He would complete His saving work upon the cross, the work which would be the basis for the thief’s salvation by grace through faith in Jesus.
Notice that Jesus said to the believing thief, “Assuredly, I say to you …” Some translations say, “Verily” and others say, “Truly.” The Greek word is a Greek spelling of the Hebrew word “Amen,” the same word that we say at the end of our prayers to express our confidence in the Lord to whom we are praying. As our Shorter Catechism says, “in testimony of our desire and assurance to be heard, we say, ‘Amen.’” Jesus said, “Truly, I say to you,” or “Verily, I say to you,” or “Amen, I say to you,” because Jesus was confident in the outcome of His ordeal of suffering because of the witness of Scripture.
Let’s now consider the fourth saying of the cross under the heading, the Cry. Jesus cried out, “My God, My God, why have You forsaken Me?” When Jesus cried out those words, He was quoting the first verse of the twenty-second Psalm, which we call the Psalm of the Cross. This is one of the passages from which Jesus in His humanity had learned that the Messiah must suffer and die and that God would deliver the Messiah from death.
This question taken from the first verse of the twenty-second Psalm is such a mysterious question as it applies to Jesus. Jesus is fully divine, and surely God cannot forsake God. And also, Jesus here addressed God as His God. How could Jesus here say, “My God, My God,” if God had forsaken Jesus? Those are good questions about Jesus’ question, and I am going to begin by stating what Jesus’ question does not mean.
This question about being forsaken does not mean that there was ever any disruption in the sweet eternal fellowship of the Godhead, in the perfect communion between the three members of the Godhead: God the Father, God the Son and God the Holy Spirit. The Great “I AM” does not change. He is the same yesterday, today and forever. No member of the Godhead is ever forsaken by any other member of the Godhead. That would be a most radical change in the very essence of God’s eternal being. Such is unthinkable.

If we humble ourselves under God’s mighty hand of sanctification, we will submit to those whom God wills. We will worship Him instead of self. We will walk by faith not by sight. That means that temptations to not be honorable can be defeated and left powerless because they depend on our functioning within our flesh and pride.

18 Pray for us, for we are sure that we have a good conscience, desiring to conduct ourselves honorably in all things. 19 And I urge you all the more to do this, so that I may be restored to you the sooner.20 Now the God of peace, who brought up from the dead the great Shepherd of the sheep through the blood of the eternal covenant, even Jesus our Lord, 21 equip you in every good thing to do His will, working in us that which is pleasing in His sight, through Jesus Christ, to whom be the glory forever and ever. Amen. Hebrews 13:18-21 (NASB) 
R.C. Sproul shared the following story in the September 2007 issue of Tabletalk magazine. “Several years ago I was participating in a discussion with some business men in Jackson, Mississippi. In the course of the conversation, one of the men made reference to a man who was not present at the meeting. He said, ‘He is an honorable man.’ When I heard this comment, my ears perked up as I thought for a moment I was hearing a foreign language being spoken. I realized that I was in the middle of the Deep South where customs of old had not entirely been eradicated, yet I still could not get over that somebody in this day and age was using the word honor as descriptive term for a human being.”
Is the term ‘honor’ as a descriptive term for a human being out of place in our day and time? If we look up ‘honor’ in our dictionaries we will find that its chief synonym is ‘integrity.’ Before we begin to determine the lack of this characteristic in the current body of Christian believers, especially among its leadership, let us define what we mean. Integrity describes one who has an uncompromising adherence to moral and ethical principles. It describes one who possesses soundness of character. There are many more definitions, but this is enough for now. A honorable person is a man or woman of principle. He or she puts principle ahead of personal gain. Also, they do not compromise their principles. That would mean that once they grasp the truth they would never let go, no matter the cost.
One of the major attacks against my posts on the doctrines of grace over the last several years was that I presented them as truth. Sometimes, this aroused some very ugly attacks because I did not say what I presented could possibly be wrong and the opposing views could be right. If I believed that then I wouldn’t have bothered posting them. What sort of truth is it that we can say, “this is the truth, but I could be wrong and your view could possible be true too.” That’s not standing on principle. That’s called compromise. Some would call it political correctness. This is why I despise our political system in the United States. Politicians must often compromise everything, including their principles in order to function. That is not right. That is why I could never hold public office.
Compromise is with us wherever we go. It seems that our entire lives are challenges to our principles. Those of us who are Christians experience this on an even higher plane. I promise you, the world system is anti-everything that God tells us from His Word that should makeup genuine Christian character.
11 “Blessed are you when people insult you and persecute you, and falsely say all kinds of evil against you because of Me.
