John 6:66 From that time many of his disciples went back, and walked no more with him.
2 Peter 2:20 For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
Then we have the parable of the sower. Some heard the word and just turned away. Then there were some who believed but later died and didn’t continue to grow. Certainly you would say that they had been called but turned back.
Matthew 13:5 Some fell upon stony places, where they had not much earth: and forthwith they sprung up, because they had no deepness of earth: 6 And when the sun was up, they were scorched; and because they had no root, they withered away.
It’s even possible to turn away after receiving the knowledge of truth
Hebrews 10:26 - For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, Hebrews 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.
So in your “predestination” scenario it gets a little murky when trying to fit those in I would suppose.
Ah, but you forgot...
Joh 6:67 So Jesus said to the Twelve, "Do you want to go away as well?"
Joh 6:68 Simon Peter answered him, "Lord, to whom shall we go? You have the words of eternal life,
Joh 6:69 and we have believed, and have come to know, that you are the Holy One of God."
Joh 6:70 Jesus answered them, "Did I not choose you, the Twelve? And yet one of you is a devil."
Our Lord knew the hearts of people. As John states, "1Jn_2:19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us.
As for 2 Peter 2:20, Matt 13:5, and Heb 10, those are not examples but doctrine. All of them talk about false prophets/believers.

I wouldn't count on it. I have a whole internet to supply me with references. ;O)
