Timeless truths about salvation. Can one lose their salvation? In other words, after being saved, can a person become lost? Here is a better question: What was the basis for your salvation? Were you saved solely based on God’s grace OR did you mix your works in with God’s grace? If you mixed your works with God’s grace to be saved, you misunderstood salvation. Clearly the Bible teaches that we are saved by grace through faith, see Ephesians 2:8-9. If you could be saved by grace plus works, then you must keep salvation by working at least a much as you did when you were saved.
Since we are saved by the grace of God, which means we do not deserve His forgiveness or love, then we are kept by the grace of God. That means you did nothing to earn your salvation and you can do nothing to keep your salvation.
Paul wrote to the church at Galatia and asked who had bewitched them. They began to believe that even though they started out by grace they were going to cross the finish line by works.
When you are saved, you are sealed by the Holy Spirit who becomes the guarantee of your salvation. See Ephesians 1.
But what about those who never demonstrate that they are born again? It may be that they were never born again in the first place. Too many people have “walked an aisle” or “prayed a prayer” but did not exercise faith! Their “salvation experience” is based on an event instead of an encounter with Jesus.
