Why does it take so long to change and grow up? There are several reasons:

· We are slow learners. We often have to relearn a lesson 40 or 50 times to really get it. The problems keep recurring, and we think, “Not again! I’ve already learned that!” But God knows better. The history of Israel illustrates how quickly we forget the lessons God teaches us and how soon we revert to our old patterns of behavior. We need repeated exposure.
· We have a lot to unlearn. Since most of our problems — and all of our bad habits — didn’t develop overnight, it’s unrealistic to expect them go away immediately. There is no pill, prayer, or principle that will instantly undo the damage of many years. It requires the hard work of removal and replacement. The Bible calls it “taking off the old self” and “putting on the new self” (Romans 13:12; Ephesians 4:22-24; Colossians 3:7-10, 14).
· Growth is often painful and scary. There is no growth without change, there is no change without fear or loss, and there is no loss without pain. Every change involves a loss of some kind. We fear these losses, even if our old ways were self-defeating, because, like a worn-out pair of shoes, they were at least comfortable and familiar.
· Good habits take time to develop. Remember that your character is the sum total of your habits. You can’t claim to be kind unless you are habitually kind. Your habits define your character.

There is only one way to develop the habits of Christlike character: You must practice them — and that takes time! There are no instant habits. Paul urged Timothy, “Practice these things. Devote your life to them so that everyone can see your progress” (1 Timothy 4:15 GW).
