That would be salvation by election and off the mark of salvation by grace through faith.
>>” and no one can wrest you out.”
No one can but you choose to leave.
No one is saved by election. Election is simply God’s plan. Men are saved by the grace of God, who, through His own free willl, chose to snatch you, a sinner, from the fires that are to come. The scripture does not say that a person that is God’s can leave Him.
