Yes, obvious. But sadly, there are actually some who teach that you can stop believing and still have eternal security. I was in church that claimed that: Their position was that if someone believed at any point in their lives, they could abandon Christianity totally (become a Moslem, for example) and still be saved. (They would just lose rewards.)

Yes, I know what you are saying. The doctrine of the perseverance of the saints is sometimes difficult to understand. The very proof that you truly believe is remaining in the faith and obedience to God’s commands. Hebrews teaches that if someone can turn apostate with no repercussions, then they probably were never truly saved. I do believe that our faith is given and maintained by God, not ourselves.
Have a blessed day!

I don’t believe that a ‘true believer’ that is ‘truly saved’ will ever stop believing and abandon Christianity. If they do, they weren’t.

Your church is correct. You are in error. We only have responsibility to fulfill the teachings of Scripture. And the Scriptures teach that, once one becomes locked in the hand of Jesus Christ, John 10:27-30, no one, including one's self, can snatch him out of That Hand.

If a person truly believes and comes to Christ, and then chooses not to believe in Christ, God still gives grace. The person is still saved. (And rewards WILL be lost.)
