Past actions are the best predictor of future behavior.  This adage is based on the observation of human behavior.  It is generally true.  However, it does not take into consideration the transforming power of the gospel when applied to a broken life.

The Bible summarizes the preaching of both John the Baptist and Jesus in these words,1 In those days John the Baptist came preaching in the wilderness of Judea, 2 “Repent, for the kingdom of heaven is at hand.” Matthew 3:1-2 (ESV) 14 Now after John was arrested, Jesus came into Galilee, proclaiming the gospel of God, 15 and saying, “The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel.” Mark 1:14-15 (ESV) The call was to repent.  This means to have a change of heart and mind that results in a change of behavior.

One of the deceitful lies of our enemy is to try to convince you that a past persistent sin defines you.
