So they ARE saved. They ARE a child of God.
If I understand you correctly, you are saying the SAVED person, who IS a child of God can somehow, by their own will, disavow that they were EVER born?
Not disavow, but simply not care about being born again anymore. That rejection of Christ--that unbelief--may take on the form of them saying "I don't think it was ever real to begin with, so I left it", or they simply find their old lives of sin more appealing and so abandon the forgiveness of God for that reason.
But in the end, either one does end up with them being incapable of believing/trusting in the gospel anymore. Charles Templeton is a classic example. After his departure from the faith, he lamented the fact that he had to convince himself the gospel was true, yet he also said he "missed Jesus". He is our living, public example of Hebrew 6:4-6/ Hebrews 10:26-31. There is no coming back for the person who has been sanctified by Jesus in a genuine salvation, but who then willfully and knowingly walks away from Christ. God does not allow it.
Again. The person was born anew. Is a sheep. Somehow rejects that he IS a sheep and morphs into a goat?
No. He simply doesn't want or care to be a sheep anymore. But he may, and probably will, convince himself in some weird reasoning that he is still okay with God. If you talk to enough unbelievers as I have, you will know this is the common path for the ex/unbelieving. They still attempt to rationalize some kind of saving saving relationship with the God they hate and do not want to serve. Few come right out and simply say, "I know the gospel is real, but I love sin more than I do righteousness."
Again. A person is a cucumber. Is Baptized (really the same term used to describe a cucumber being dipped into a vinegar solution to become a pickle) by the Holy Spirit, and becomes a pickle, and then somehow by it's own will becomes a cucumber again?
Yes, I know. It's impossible for you to see that the born again experience is simply having the Holy Spirit come into you and that it's not a brand new person being created, but simply a 'new' you by virtue of God's presence being right in your inner being coaching you into a new way of thinking and acting. I blame the church for portraying the born again experience as if a new and separate creation has been made with his own birth certificate and substance which can not be denied or reversed like a natural baby's birth.
You see, the church is business. It has to sell to stay in existence. Preachers just don't go, "oh well, no one's here to hear and cherish the true word of God today, so there's no money in the bucket to pay my salary this week." No. Instead they make sure they speak and perform in a way that tickles your worldly appetites so you'll fill the pews and make sure he gets paid that week. This has been going on for centuries. That's why I blame the leadership for the bad state we're in right now. They are the ultimate blame, for not teaching the truth.
Can't you see how silly it is to believe one day you were Born again, a NEW creation, and then by your will, UNBORN
yourself?
Yes, it's so hard to imagine that the Holy Spirit can move out of a person as simply and as easily as he moved in, lol. You're only 'new' because the Holy Spirit is in you, not because you're a new and separate entity created by God that can't be denied as existing or having ever existed, like a new baby born into your natural family.
