The answer to this question is a simple “No”. People who teach OSAS forget he who endures to the end will be saved.
If we endure, we will also reign with him. If we disown him, he will also disown us; (2 Timothy 2:12).
This verse is clear if we disown God he will disown us. This is made clear in other passages to.
The Lord is with you while you are with Him. If you seek Him, He will be found by you; but if you forsake Him, He will forsake you (2 Chron. 15:2).
And remember what Jesus said “IF you deny me in front of men I will deny you in front of my Father”.
Once saved always saved/P from the TULIP is false as can be.
Jesus said to him, “No one, having put his hand to the plow, and looking back, is fit for the kingdom of God.”( Luke 9:62). Let us remember this.
