Many in the religious world today proclaim that a child of God cannot fall from grace, also known as “once saved, always saved.” This teaching is not consistent with Biblical teaching. It is also said that if a child of God does fall away then that person was never saved in the first place.
In 1 Corinthians 10:12 the apostle Paul says, “Therefore let him who thinks he stands take heed lest he fall.”
In 1 Corinthians 9:27 Paul says, “But I discipline my body and bring it into subjection, lest, when I have preached to others, I myself should become disqualified.”
Prior to this statement Paul likens the Christian walk to a race and says that one should run in such a way to obtain the prize. If one decides not to finish the race then one can not win. This implies that one can begin, but not finish the race. All of this in reference to the Christian walk.
In Galatians 5:4-7, Paul speaks of those who were trying to be justified by the Law of Moses. He then concludes that those who tried to do such had “fallen from grace.” With this in mind, one cannot fall from where he never was.
Paul speaks of a man by the name of Demas in 2 Timothy 4:10. This man had forsaken Paul because he loved the world. He also references two other men in 1 Timothy 1:18-20, Hymenaeus and Alexander. The faith of these men “suffered shipwreck” (1 Timothy 1:19). Thus, they had fallen from grace.
Simon the sorcerer in Acts 8:9-24 had become a Christian, but sinned. He was told to repent and pray. If this was not done then he would have continued having the sin that he had committed.
In conclusion a child of God can fall from grace. However, if a Christian continues to walk in the light 1 John 1:5-10, then the blood of Christ will continually cleanse him. If a child of God chooses to cease to walk in the light then he has fallen from grace and the blood of Christ will no longer cleanse him.
