Galatians 5:4

4 Those of you who try to be put right with God by obeying the Law have cut yourselves off from Christ. You are outside God's grace.

Galatians 5:4 Meaning and Commentary

Galatians 5:4

Christ is become of no effect unto you
Or "ye are abolished from Christ"; or as others by an "hypallage" read the words, "Christ is abolished unto you"; for by their seeking for justification by their own works, it was all one to them as if there was no Christ, and no righteousness in him, and no salvation by him; they had nothing to do with him, nor he with them:

whosoever of you are justified by the law;
that is, who sought to be justified by their obedience to the law, or who thought they were, and trusted in themselves that they were righteous; for otherwise, by the deeds of the law, no flesh living can be justified:

ye are fallen from grace;
that is, either from that grace which they professed to have; for there might be some in these churches, as in others, who were only nominal Christians, and formal professors; who had declared they saw themselves lost and undone sinners, destitute of a righteousness, and professed to believe in Christ alone for righteousness and strength, but now trusted in themselves, and in the works of the law: or from the scheme of grace in the whole of man's salvation, which will admit of no mixture of works; either it is one or the other, it cannot be both; wherefore by their taking on the side of works, they showed that they had entirely dropped the scheme of grace: or else from the Gospel of the grace of God, from whence they were removed, through the influence of false teachers; particularly the doctrine of free justification by the grace of God, through the righteousness of Christ; which was entirely set aside by their seeking to be instilled by the works of the law; and from this they might be said to be fallen, who were on such a bottom.

Galatians 5:4 In-Context

2 Listen! I, Paul, tell you that if you allow yourselves to be circumcised, it means that Christ is of no use to you at all.
3 Once more I warn any man who allows himself to be circumcised that he is obliged to obey the whole Law.
4 Those of you who try to be put right with God by obeying the Law have cut yourselves off from Christ. You are outside God's grace.
5 As for us, our hope is that God will put us right with him; and this is what we wait for by the power of God's Spirit working through our faith.
6 For when we are in union with Christ Jesus, neither circumcision nor the lack of it makes any difference at all; what matters is faith that works through love.
