Well:
"...who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit, and have tasted the good word of God and the powers of the age to come..."
Seems pretty clear. Takes a lot of gymnastics to turn that into a description of someone who has never believed.
“Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter.
“Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?’
“And then I will declare to them, ‘I never knew you; DEPART FROM ME, YOU WHO PRACTICE LAWLESSNESS.’
So were they ever saved, or not?
Not necessarily so.
I know of people who have heard the gospel, many times, have experienced God's work in their lives and seen miracles, and STILL resist and fight God.
They are people who have experienced the work of God in their lives as He has reached out to touch them and yet, even some of those people will continue to reject God.
Judas is a prime example.
He was one of the Twelve and was sent out to preach and perform miracles.
Jesus gave him the same ability as the other apostles. He partook and was certainly enlightened to a degree and chose to reject.
Jesus never spoke of him in a way that indicated that He considered him saved.
*Son of perdition* I believe is the term Jesus used.
Indeed!
