A tweet from the theologian Miroslav Volf (there are occasionally some good things on Twitter):
“Repentance is not a mere neutral zone between evil and good through which those who have committed wrongdoing must pass in order to return to the good. In repenting, I am differentiating myself from my wrongdoing; I am embracing the good in renouncing my wrongdoing.” 
We repent of our sins not to dwell upon them or wallow in them; but to confront them head-on, to separate ourselves from the evil we have done, and most importantly to turn to God.
