“You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace.” (Galatians 5:4, NKJV)
Can a Christian be lost in sin after being saved in Christ? Calvinism says, “No.” Reportedly, so did Billy Graham: “Returning home with a friend that night, Mr. Graham said, he thought: “Now I’ve gotten saved. Now whatever I do can’t unsave me. Even if I killed somebody, I can’t ever be unsaved now” (nytimes.com, Feb. 21, 2018). But, the apostle Paul told Christians, “Yes.” He said an attempt to be justified by law-keeping (the law of Moses, Galatians 2:21, 3-7) would cause them to be “estranged from Christ” and “fallen from grace.” That’s clear enough. The doctrine of “once saved, always saved” gives false comfort because it does not conform to the Scriptures. Jesus warned of those who would joyfully “believe for a while and in time of temptation fall away” (Luke 8:13). Christians are told to “Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God” (Hebrews 3:12). And so, we are urged to “exhort one another daily…lest any of you be hardened by the deceitfulness of sin” (Hebrews 3:13). “Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience” (Hebrews 4:11). A Christian who does not repent and pray God’s forgiveness for sins committed, will not be saved (Acts 8:18-24; 1 John 1:9). The Scriptures must inform and sustain our faith.
