Actually, that too is part of the Law of Moses...if you should be so inclined to look. But, please, if you do, and come to settle on this being "Christian Living 101", then do not, under any circumstance, fail to include Matt. 5:48 in your efforts to follow the requirements...and let us know when you are satisfied with your success. Regards.
That's why I quoted it. It's interesting that it's so consistent with what Paul says about us being "created in Christ Jesus to do good works". But maybe Paul wasn't talking about "Biblical Christianity?"
