Here is the entire verse as given in Galatians 5:4, "Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace". The verse is self-explanatory. If a person is trying to justify themselves by keeping the law, then they have turned away from being saved through God’s grace, through faith in Christ alone. God brought salvation to mankind by His grace in sending Jesus Christ to pay for our sins. (Titus 1:11).

Salvation is offered as a free gift to anyone who will receive it by faith in Jesus Christ, believing that He died and rose again in payment for their sin. Ephesians 2:8,9 states very plainly, "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: NOT OF WORKS, lest any man should boast." Galatians 5:4 does not teach that you lose your salvation; but, rather, that you do not have salvation when you turn, or "fall away", from God’s offer of grace and try to justify yourself by good works.

"He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him." (John 3:36).
