Charles Ellicott Commentary Galatians 5:4

"Ye are severed from Christ, ye would be justified by the law; ye are fallen away from grace." — Galatians 5:4 (ASV)

Christ is become of no effect unto you.—Literally, You were (or, more idiomatically, are) abolished, made nothing, from Christ; a condensed form of expression for, You are made nothing (unchristianized), and cut off from Christ. Your relations to Christ are cancelled, and you are Christians no longer.

Are justified.—Strictly, seek to be justified.

You are fallen from grace.—The Christian is justified by an act of grace, or free, unearned favor, on the part of God. He who seeks for justification in any other way loses this grace. Grace is not here a state or disposition in the believer, but a divine act or relation.
