When I find discussions like this as is common on every talk site I've joined or read, I think of what would Jesus say if he read it?
I think Paul gave his answer long ago. And sad as it is even his words have been used and reinterpreted so to sustain the wrong headed argument that insists eternal salvation is a myth.
Hebrews 6:4-6
4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost, 5 And have tasted the good word of God, and the powers of the world to come, 6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.

If Jesus sacrifice didn't cover our sins eternally, if we are not reborn from a state where in we were eternally lost but for that sacrifice, and having tasted that heavenly gift being sealed by God's Holy Spirit for all time, and consequently are able to be lost by our own choice or behaviors as we were before Jesus saved us, then that fact and we put our savior to become an open shame faced poser when claiming himself savior who gives eternal life.
Which means the same thing as eternal salvation because without salvation we are subject to the eternal state of a second death.
And there is I think the pivotal part of the true gospel that shuts the door on the eternal salvation is a myth argument.
Even though I've read on other sites the argument that insists eternal life is a condition separate and apart from salvation.
I think that a silly thing to say. But I think it not unusual if it accompanies the point of view that attempts to put Jesus to open shame when it is thought he did not die to bring us into his eternal saving grace.
I don't believe God's teachings can make a dent so to change the mind that lives a false faith in conditional reprieve and reward.
Because when the gospel is turned on itself by those teachers and believers in the shame teaching who insist their choice overcomes God's promise, they cannot hear the truth of God's words through Christ. Because the ego is still in love with itself in them.
Many will call the name Jesus. That doesn't mean God knows them by name.
