Repentance is a paradox. The word describes a change of pattern based upon a change of direction.
The Christian use of the word describes turning away from sin in order to turn toward God. This change of direction is initiated by your human will, but empowered by God.
The change of pattern is another problem. We habitual creatures have a way of returning to our past patterns. And hence the reason why I call repentance a paradox. We make a commitment to God to turn from sin, knowing full well we will continue to sin despite our efforts.
But don’t take my statements as asserting there is a falsehood in repentance. It is a real and necessary part of the Christian experience. We make a decision to turn our lives over to God. God then gets a grip on us. His actions place us into His family and kingdom, but they do not remove our humanity. Our free will is a major ingredient in our humanity so removing it would be making us something less than human.
This paradox is necessary because it is God’s desire to have a relationship with humanity. Not creatures without free will, but real people with all their failings. For this reason the Christian life is more one of grace and forgiveness than the conquering of sin.
Please don’t misunderstand me. I am not saying sin all you want, or sin doesn’t matter. I want you to work hard to battle sin. In this battle you can expect to gain ground. You can expect to prevent sin from overtaking you and robbing you of your freedom or usefulness to God. But you cannot expect to gain absolute victory by never sinning again.
