I wonder if you have ever run across any teaching on eternal security that takes what’s called a “3rd view”, as distinct from both loss of salvation and OSAS.
One teacher, in particular, uses Hebrews 6 to point to the fact that IF we can be categorized as having tasted of the good things of the Lord, and then become, by choice, apostate, God is not going to take us to live forever with him because He honors our right to choose – not because we need to be punished.
Do you see any circumstances under which having once been saved, we can go to a lost eternity? How do you feel about God taking us to Himself “against our will”? Any enlightened person would not choose to go to hell!!
There are two passages that clearly contradict this man’s view, which as far as I know is unique to him.
The first is John 6:38-40 where Jesus promised not to lose even one of us. He’s our shepherd and we’re His sheep. Sheep are prone to wandering and it’s the shepherd’s responsibility to keep them. This is born out by 2 Cor 1:21-22 where Paul wrote that it’s God who makes us stand firm. He set His seal of ownership on us and has guaranteed our inheritance.
Once we’re saved it becomes God’s responsibility to keep us that way and He has guaranteed us that He’ll do it.
No true believer would ever turn away from our blessed hope. As Peter said, “Lord, to whom should we go? You have the words of eternal life.” (John 6:68) And John wrote, “If they had belonged to us they would have remained with us. Their going showed that none of them belonged to us.” (1 John 2:19)
