But now that we know this, we must work..

Lev 20:26 ESV - 26 You shall be holy (set apart) to me, for I the LORD am holy and have separated you from the peoples, that you should be mine.

1Pe 1:15-16 ESV - 15 but as he who called you is holy, you also be holy in all your conduct, 16 since it is written, "You shall be holy, for I am holy."
