'Nullify' in the Bible

What then? If some did not believe, their unbelief will not nullify the faithfulness of God, will it?

Do we then nullify the Law through faith? May it never be! On the contrary, we establish the Law.

and the base things of the world and the despised God has chosen, the things that are not, so that He may nullify the things that are,

I do not nullify the grace of God, for if righteousness comes through the Law, then Christ died needlessly.”

What I am saying is this: the Law, which came four hundred and thirty years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise.
