The Cure for a Lack of Fruit in Our Christian Lives

The Cure for a Lack of Fruit in Our Christian Lives

There is only one cure for a lack of fruit in our Christian lives. It is to go back to Christ and enjoy (yes, enjoy) our union with Him. 

The Westminster Confession of Faith insists that Christians may be “certainly assured that they are in the state of grace” (18:1) and goes on to assert that this “infallible assurance of faith” is “founded upon” three considerations:

  1. “the divine truth of the promises of salvation”
  2. “the inward evidence of those graces unto which these promises are made”
  3. “the testimony of the Spirit of adoption witnessing with our spirits that we are children of God” (18:2).

The possibility of “certain” and “infallible” assurance is set against the backdrop of medieval and post-Reformation Roman Catholic views that paralyzed the church with an “assurance” that was at best “conjectural” (wishful thinking), based as it was on rigorous participation in a sacramental treadmill. Few epitomized the contrast more starkly than Cardinal Bellarmine (1542–1621), the personal theologian to Pope Clement VIII and ablest leader of the Counter-Reformation, who called the Protestant doctrine of assurance “the greatest of all heresies.” What, after all, could be more offensive to a works-based and priest-imparted system of salvation than the possibility that assurance could be attained without either? If Christians can attain an assurance of eternal life apart from participation in the church’s rituals, what possible outcome could there be other than rampant antinomianism (the belief that God’s commandments are optional)?

But what exactly did the Westminster divines mean when they implied that our assurance is “founded upon” inward evidence? Behind this statement lies a practical syllogism:

(major premise) True believers demonstrate the fruit of the Spirit.
(minor premise) The fruit of the Spirit is present in me.
(conclusion) I am a true believer.

It should be obvious that the subjectivity of this argument is fraught with difficulty. While the certainty of salvation is grounded upon the (objective) work of Christ, the certainty of assurance is grounded upon the (objective) promises God gives us and the (subjective) discovery of those promises at work in us. And it is this latter consideration that gives rise to one or two problems.

Theologians have made a distinction between the direct and reflexive acts of faith. It is one thing to believe that Christ can save me (direct act of faith). It is another thing to believe that I have believed (reflexive act of faith). Apart from the first consideration (that Christ is both willing and able to save) there can be no assurance of faith. Indeed, it is pointless to move forward with the discussion about assurance apart from a conviction of the truthfulness of this statement: “Christ is able to save those who believe.”

Assuming, then, that there is no doubt as to the ability and willingness of Christ to save those who believe, how may I be assured that I have this belief? The answer of the New Testament at this point is clear: there is an “obedience of faith” (Rom. 1:516:26). True faith manifests itself in outward, tangible ways. In other words, the New Testament draws a connection between faithfulness and the enjoyment of assurance. True believers demonstrate the fruit of the Spirit, and this fruit is observable and measurable.

Four Ways of Knowing

The Apostle John addresses this very issue in his first epistle: “I write these things to you who believe in the name of the Son of God that you may know that you have eternal life” (1 John 5:13). Apart from belief “in the name of the Son of God,” there is no point in furthering the discussion about assurance. The question at hand is, “How can I know if my belief is genuine?” And John’s answer emphasizes four moral characteristics of the Christian life.

First, there is obedience to the commandments of God. “By this we know that we love the children of God, when we love God and obey his commandments. For this is the love of God, that we keep his commandments” (1 John 5:2–3). True faith is not and can never be antinomian.
