My concern was because of the false brothers [those people masquerading as Christians] who had been secretly smuggled in [to the community of believers]. They had slipped in to spy on the freedom which we have in Christ Jesus, in order to bring us back into bondage [under the Law of Moses].

yet we know that a man is not justified [and placed in right standing with God] by works of the Law, but [only] through faith in [God’s beloved Son,] Christ Jesus. And even we [as Jews] have believed in Christ Jesus, so that we may be justified by faith in Christ and not by works of the Law. By observing the Law no one will ever be justified [declared free of the guilt of sin and its penalty].

For if I [or anyone else should] rebuild [through word or by practice] what I once tore down [the belief that observing the Law is essential for salvation], I prove myself to be a transgressor.

Why, then, the Law [what was its purpose]? It was added [after the promise to Abraham, to reveal to people their guilt] because of transgressions [that is, to make people conscious of the sinfulness of sin], and [the Law] was ordained through angels and delivered to Israel by the hand of a mediator [Moses, the mediator between God and Israel, to be in effect] until the Seed would come to whom the promise had been made.
