We aren’t born again to stay the way we are. But how many times have we looked around us in dismay at the lack of spiritual maturity in fellow believers, and in us? It is evident in the rising rate of divorces among Christian couples. We find it in the high percentages of Christians who regularly view pornography. And we face it each time a well-known Christian leader is found in sexual sin or handling finances dishonestly. Perhaps you have struggled with your own character issues for years, even decades, to little avail. You can experience significant growth in your Christian walk, shed sinful habits, and increasingly take on the character of Christ. In Renovation of the Heart, Dallas Willard calls it ​“the transformation of the spirit” – a divine process that ​“brings every element in our being, working from inside out, into harmony with the will of God or the kingdom of God.”
