When is the last time you heard a sermon that suggested that a motive for our obedience should be the rewards we receive in heaven? I imagine for most of us it has been a long time, maybe even never. Whenever a sermon (or book) provides a motive for obedience, it is almost always thankfulness for what Christ has done. And certainly that is a wonderful and foundational motivation. But is it the only motivation?
The New Testament writings suggest it is not. For those who faithfully endure persecution, Jesus makes it clear, “Rejoice in that day, and leap for joy, for behold, your reward is great in heaven” (Luke 6:23). Paul states it plainly, “But each will receive his own reward according to his own labor” (1 Corinthians 3:8). The author of Hebrews even reminds us that Moses was motivated by rewards, “He regarded disgrace for the sake of Christ as of greater value than the treasures of Egypt, because he was looking ahead to his reward” (Hebrews 11:26).
But if rewards are clearly presented as a motivation in the Christian life, why don’t we hear more about rewards in our modern pulpits? I am sure there are many answers to that question, but let me suggest one: we have been convinced that our obedience doesn’t matter. While we are rightly told that only Christ’s obedience can secure our justification and that he has kept the law perfectly for us, our own obedience receives far less attention in the pulpit. Justification is center stage, and sanctification is peripheral.
No doubt, the downplaying of Christian obedience is borne out of good motives—some think Christ is glorified the most when we disparage our own obedience. Our good works are just “filthy rags” (Isaiah 64:6), we are reminded.
But, this whole line of thought misses the distinction between an unbeliever’s attempts at law-keeping and that of regenerated believer. Granted, neither can merit salvation or justification. Both fall woefully short of God’s perfect standards. But that does not mean that the believer’s obedience doesn’t matter. God can still be pleased with it, even though it is imperfect. Consider John Piper’s comments on this point:
It is terribly confusing when people say that the only righteousness that has any value is the imputed righteousness of Christ. I agree that justification is not grounded on any of our righteousness, but only the righteousness of Christ imputed to us. But sometimes people are careless and speak disparagingly of all human righteousness, as if there were no such thing that pleased God. They often cite Isaiah 64:6 which says our righteousness is as filthy rags…[But] when my sons do what I tell them to do—I do not call their obedience ��filthy rags” even if it is not perfect. Neither does God. All the more because he himself is “working in us that which is pleasing in his sight” (Hebrews 13:21). He does not call his own, Spirit-wrought fruit, “rags” (Future Grace, 151-152).
It is only when we recognize that the obedience of the believer really does matter, and that we really can please our Father, that the rewards passages in the Bible will make any sense. And that can be a tremendous encouragement to those of us who labor heavily in ministry. When we toil for the cause of Christ, we want to hear, and are bolstered by hearing, the encouraging words of Paul: “Your labor is not in vain” (1 Corinthians 15:58).
