The principle of capacity teaches us that believers have varying levels of spiritual capacity, and our role as leaders is to recognize and nurture that capacity, not to expect everyone to reach the same level of fruitfulness. By understanding this principle, we can avoid disillusionment and find joy in the growth of each believer, no matter their level of fruitfulness.

I first heard Darrell Champlin preach in 1987 at our a little home church in Atkinson, New Hampshire. He and his wife Louise were supported by Pentucket Baptist Church, where we were members, pastored at the time by Dan Sherman.
Darrell was the guest speaker our annual missions conference – I listened to his one-hour-fifteen minute expositional sermons filled with references to the glory, sovereignty and majesty of the “God of Heaven”, and illustrations of a God who works to save the lost in hard places, on the edge of my seat!
One of the sermons I heard Darrell preach was, The Principle of Capacity. I have taken great liberty to edit his sermon in this post, because the lesson contained here has been one that has been of great help to me through the years of service to Christ in Africa.
A Needed Ministry Principle
As missionaries and pastors, we often struggle with two areas related to capacity. The first is our hearers’ response to evangelism, and the second, perhaps more challenging, is their response to discipleship and the spiritual growth of new converts.
When it comes to evangelism we recognize the hardness of the human heart and the miraculous work of the Holy Spirit required for a lost sinner’s salvation. While we long for the salvation of the lost and invest much effort and prayer toward that end, we don’t necessarily expect all or even a majority to turn to Christ as Savior. We rejoice when some come to God, understanding the challenges inherent in evangelism, and the sovereignty of God in drawing men to repentance and faith.
Capacity in Discipleship
However, the matter of discipleship is a different story. Countless pastors and missionaries have become discouraged and disillusioned due to the perceived failure of converts to demonstrate growth and obedience to the Word of God. Much of this disillusionment could have been avoided if they had understood the principle of capacity.
The Parable of the Sower
In Matthew 13:23, Jesus describes what He calls “good ground” – hearts where the gospel takes root and bears fruit.

The Valley of Vision – Various authors, edited by Arthur Bennett. This has long been one of my favourites.  This is a collection of prayers from Puritans and Puritan-minded folks.  Prayers are here from Thomas Watson, John Bunyan, Charles Spurgeon and many others.  My only complaint about this volume is that it doesn’t tell you where the prayers are from or who wrote which prayers.  

Over the years, I’ve received many requests from people looking for devotional literature. The one person wants a book of devotions for retired couples. The other wants a book for engaged couples. Still another is looking for something for their teenager. I used to search high and low for things I could recommend for these niche needs. No longer.
Now I recommend that people just start with reading the Bible prayerfully.  Why is it that everyone feels they need someone to make the Bible relevant for them?  It’s almost as if we’ve returned to the stereotype of the medieval church:  everyone talks about the Bible but no one reads it for themselves.  The Bible seems to have become a mysterious book which someone else has to interpret and apply for us.
Not to Replace Scripture but Supplement
That said, there is a place for devotional literature.  There is a place for authors to share their meditations on sacred Scripture.  There is a place for us to learn from our forebears how to pray and think Christianly.  Yet these things ought never to replace our going directly to the source for ourselves.  They should be supplementary.
Moreover, I wish we could lose this idea of niche devotionals — the devotional for the unemployed single mother, the devotional for the engaged couple, etc., etc.  This trend is reflective of the narcissism of our day:  everyone needs something crafted exactly for their personal, individual needs.  Whatever happened to the Catholic Church?  Whatever happened to the communion of saints?  Whatever happened to being able to think and apply general truths to your individual needs?
Types of Devotionals
There are different types of devotionals.  There’s your traditional devotional which has a reading for each day of the year.  Usually each day has a Bible passage to read, often just a verse or two.  Most of the time the author expounds and applies that Bible passage, although there are now some devotionals which might rarely or not at all involve a reading from the Scriptures.
There are also devotional books developed out of sermons.  These books go into depth with one or more Scripture passages.  The purpose is not primarily intellectual, but spiritual and transformative.  The Puritans and other older writers are well-known for this type of literature.
Finally, there are devotional books composed of prayers.  You can read through these in a meditative fashion and then use them as the starting point for your own prayers.  You can also pray them for yourself as they’re written.  A deeper and richer prayer life can be gained by listening in to other saints’ communication with our God.
Cautions with Devotionals
Besides the niche concern, I see three other prevalent issues with devotional books.  The first is one I hinted at above:  devotions disconnected from the Bible.  Beware of devotional books which are just presenting an author’s ideas.  Those ideas may be based on the Bible and consistent with the Bible, but the less explicit that becomes the greater the risk of not being able to discern truth from error.

Jesus is everywhere in the Bible. He is the meaning and purpose of every word, every story, every book, every genre, every section, every theme, every figure, every image, and every storyline. When you realize that, the Bible becomes like the movie, The Sixth Sense. Once you know the ending, you can’t help but see the clues all along the way. You see it everywhere. We need to develop a sixth sense for Jesus.

The Reformer Martin Luther said, “Take Christ out of the Scriptures, and what will you find remaining in them?”[1] But seeing Jesus in the scriptures isn’t easy. It’s not automatic. Some of the greatest Bible readers in history have failed to see him. The Pharisees were the most proficient and diligent Bible readers in the history of the world. Yet what does Jesus tell them? John 5:39, “You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me.”
      The Pharisees weren’t the only ones missing the point. Jesus’s disciples did too. After Jesus’s resurrection, Luke 24:13-27 tells the story of two disciples on the Emmaus Road. Jesus approached them, unrecognized, and asked them what they were discussing. They said, “Well, we thought Jesus was the Messiah, but he was crucified, so I guess we were wrong.” Jesus responded with a reprimand, saying, “O foolish ones, and slow of heart to believe all that the prophets have spoken! Was it not necessary that the Christ should suffer these things and enter into his glory?” Then he does something amazing. “And beginning with Moses and all the Prophets, he interpreted to them in all the Scriptures the things concerning himself.”
The Bible is one big, unified story about Jesus. Remove him, and you have nothing left.
I’m arguing for a Christocentric reading of the Bible because I think that’s what the Bible itself argues for.
Now, here’s what I’m not saying. I am not saying you can see Jesus’s name in every verse. You can’t even see it in every chapter. You can’t even see it in every book of the Bible. Esther doesn’t mention God’s name. But think of it like a trajectory. The tension builds with every story.
A Christocentric view of the New Testament isn’t as difficult because Jesus is mentioned by name so often. But what about the Old Testament? Though he is not named, we see Jesus everywhere. We find the pattern of Jesus—a Savior rising to redeem God’s people. We hear the promise of Jesus—one to come that will undo the curse and bring the blessing. We feel the presence of Jesus—divine help amid God’s people in all their struggles and sins.[2]
As Tim Keller famously summarized it, Jesus is the true and better everything.

Jesus is the true and better Adam who passed the test in the garden and whose obedience is imputed to us.
Jesus is the true and better Abel who, though innocently slain, has blood now that cries out, not for our condemnation, but for acquittal.
Jesus is the true and better Abraham who answered the call of God to leave all the comfortable and familiar and go out into the void not knowing wither he went to create a new people of God.
Jesus is the true and better Isaac who was not just offered up by his father on the mount but was truly sacrificed for us. And when God said to Abraham, “Now I know you love me because you did not withhold your son, your only son whom you love from me,” now we can look at God taking his son up the mountain and sacrificing him and say, “Now we know that you love us because you did not withhold your son, your only son, whom you love from us.”
Jesus is the true and better Jacob who wrestled and took the blow of justice we deserved, so we, like Jacob, only receive the wounds of grace to wake us up and discipline us.
Jesus is the true and better Joseph who, at the right hand of the king, forgives those who betrayed and sold him and uses his new power to save them.
Jesus is the true and better Moses who stands in the gap between the people and the Lord and who mediates a new covenant.
Jesus is the true and better Rock of Moses who, struck with the rod of God’s justice, now gives us water in the desert.
