For me when I look at all God's Law, even the Law of Moses, I see that God gave all Law to teach one thing, 'what love looks like.' Don't do this because it not an expression of love. Do, do this because it is an expression of love.'
Moses Law is an expression of the Messiah's love, in shadows, that we literally walk out when we walk in the Spirit of grace.
When the law says, the murder shall be put to death. That says to me that murder is not an expression of love and it is in fact so terrible there is no way to make amends for it. God must give one abundant mercy, grace, and love to the murder who repents.
I think this is using the law, lawfully.
Well said,
