We have the miracle of repentance. This miracle has come through Jesus Christ, our Savior. All believers will struggle with that old rotten thing that still hounds us. It's called our sin nature. However, there is now a new discipline that God has destined for all who belong to him. "If we confess our sins, he is faithful and just and will forgive us our sins and cleanse us from all unrighteousness" (1 John 1:9).
This is not a righteousness of our own. We are bought with a price. The price paid defies calculation. The best thing to do is trust and obey. There is no other way. All believers have the calling of the discipline of repentance. Everyone who belongs to Christ must learn to walk this miracle road of repentance.
