​The Law given as part of the Old Covenant is no longer in force (including the Decalogue), since the Old Covenant no longer is in force.

However, the moral precepts which undergird the laws of the Old Covenant still apply.

That’s because God’s overarching command – re-stated multiple times in both the Old and New Testament – to “be holy for I am holy” still applies.

God’s nature does not change, and neither have His moral precepts …

Which He’s revealed through all of Scripture as part of His own self revelation.
