Part of the Gospel reading for Laetare Sunday.
It would seem to harmonize very well with the epistles of John, that one who loves God will keep His commandments, and that one who sins knowingly but claims to love God lies. If God draws us to Himself, does He not help us know that we sin? Would He really let us remain ignorant, if He wants us to be perfect? And if we know that we are sinning against God, but prefer sin to God, do we not reject His grace of conversion in order to continue to sin "comfortably"?
