Realize that you can't keep your promises. That may seem like a strange first step toward the goal of keeping promises, but it's true.
Consider this question: If we could keep our promises, wouldn't we have done it by now? How many times have we made the same promises? Let's face it, rededication to keep promises won't work. If it did, we wouldn't find it necessary to keep rededicating ourselves. Many of us have struggled with promise-keeping for one reason: We have focused on our performance more than on Jesus Christ. We have tried to keep our promises, but the Bible teaches that effective Christian living doesn't come by trying. It comes by trusting Christ to express his life through us. He is the only One who can successfully keep promises.
Before we can be effective promise keepers, we must become promise receivers. The Bible is clear about God's promise: the One who has given us his life will be the One who lives it for us. Only Jesus Christ can effectively live the perfect life. He lives inside believers today and wants to reveal His perfect life through us.
