Repentance is not behavior change because biblically speaking, repentance is a change of mind. What you do results from what you think and therefore repentance affects not the symptom (works) but the disease (thinking). Of course, all Christians are not called to delight in sin but to pursue holiness.

A proper understanding of repentance is crucial for Christians to have because if they equate repentance to "performance" they will suffer from a joyless life crushed by undue burden of guilt, shame, misery and despair. It is not man who atones for his own sin; only Christ's sacrifice at Calvary is sufficient to do that.

Our Scripture focus will be Mark 1:15.
