Excellent writing - just excellent. This is so true.
I have often felt by God not to allow any sin to "worry" us beyond just beyond "get up and go."
These concepts are things that I have to refresh again and again all the time. One dimension of the problem is that the world (people around us) are not so forgiving at all and can tempt us to "repent wrong" as you put it.
Thanks for posting this! Good read.
