'Sins' in the Bible

for through the Messiah, God was reconciling the world to himself by not counting their sins against them. He has committed his message of reconciliation to us.

and that upon re-visiting you I may be humbled by my God in your presence, and may have to mourn over many whose hearts still cling to their old sins, and who have not repented of the impurity, fornication, and gross sensuality, of which they have been guilty.

Those who cling to their old sins, and indeed all of you, I have forewarned and still forewarn (as I did on my second visit when present, so I do now, though absent)
