While I totally understand and agree when it comes to our bodies ascgiven from birth, I question whether Leviticus 19:28 should bind the conscience now that Christ by His marks has redeemed all flesh.
In other words, that directive applied in view of Jewish ceremonial law, which has been fulfilled. I hearken to maintaining my body as given regardless of this verse.
Jesus was an OBSERVANT JEW, when HE was a human and not only followed Biblical laws, but wanted everyone else to.
