Once a person receives Christ as Savior, can that same individual lose salvation? Sadly, there are multitudes of Christians who believe in the possibility of losing their place in Heaven. Those of different religions are constantly worried whether they are truly saved or not, so they try to keep their salvation through their good works. But nowhere in the Bible does it say that a saved soul under the Church Age can go to Hell when failing to stay faithful to God. No matter what sin that a believer commits in the future, God secures His child permanently. Nothing and no other being has the power to take away the salvation of a saint. This wonderful promise of God is known to many as "eternal security." Observe the following verses:
I John 5:11-13: God said that once you believed on Christ, you have eternal life. “Eternal” means “forever.” Plus, God says that this life is a record (vs. 11). Once something is recorded and eternal, you can’t erase it away. God also says that once you believed, you know that you are saved (vs. 13). It’s impossible to lose your salvation.
I Corinthians 12:12-27: The Bible says that you are a member of the body of Christ. God said it is impossible to lose a member of Christ’s body. God also said that there is no schism in the body of Christ (vs. 25); so, no matter what sin you may commit, you are still clean from sin.
Ephesians 1:13: The Bible says once you believed on Christ, you are sealed by the Holy Ghost. Never did the Bible say that once you are sealed, the Holy Ghost can un-seal you. Once the Bible says you are sealed, you are sealed! Nothing more or less. Once the Holy Ghost seals you, there is no possible way that you can un-seal and overpower God the Holy Ghost.
John 1:12: God says that once you received Christ, you are a son of God. Let me ask you, “If your father bore you, you are his son, right? Let’s say that you hate your father and you separate yourself from him. Does this mean that you are still not his son?” Of course, not! It’s the same thing with God and you. Since you are God’s son, you cannot undo your “son-ship” from God.
Romans 8:38-39: God said that absolutely nothing in this universe, life, or time can separate you from the love of God in Christ Jesus. You cannot separate yourself from Christ with anything, no matter how hard you try.
John 10:27-30: Christ and God the Father have you in their hands. Christ said once you belong to Him, no one can pluck you out of His or God the Father’s hands. It is impossible then that anyone or anything can have the power to pluck you out of God’s hand.
Colossians 2:11-12: Once you have accepted Christ by faith, you are cut off from your sins. No matter what kind of “unforgivable” sin you may commit, you still have no sins in you. You’re forgiven from all sins in the past, and you are free from all sins in the future. You are saved, even if you commit the most numerous or heinous sins.
