Matthew 5:18
For it is true when I say, not one little letter or even a portion of a letter will be removed from the law of Moses until everything is accomplished [that is required by them]. [When that happens, then] heaven and earth will pass away [i.e., be destroyed. See II Peter 3:12].
Revelation 15:3
And they were singing the song of Moses, the servant of God, and the song of the Lamb. [The words were], "Your deeds are great and marvelous, O Lord, God Almighty; your ways are just and true, O King of the nations [or, "ages"].
Romans 3:31
Do we then [intend to] destroy law [observance] because faith [in Christ is now required]? Certainly not! But [instead], we uphold [the validity of] law.
Romans 7:12
So, the law of Moses itself is holy and the commandment [against sinning] is holy and just and good.
