“Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.”
King James Version (KJV)
5:4 Therefore Christ is become of no effect to you - Who seek to be justified by the law. Ye are fallen from grace - Ye renounce the new covenant. Ye disclaim the benefit of this gracious dispensation.
Ga 5:4 Christ is become of no effect unto you. If you be circumcised in order to keep the Mosaic law. See PNT "Ga 5:2". Ye have fallen from grace. By resorting to the law for salvation.
