John 15:4-6

15:4 Remain in me, and I will remain in you. Just as the branch cannot bear fruit by itself, unless it remains in the vine, so neither can you unless you remain in me.

15:5 “I am the vine; you are the branches. The one who remains in me – and I in him – bears much fruit, because apart from me you can accomplish nothing. 15:6 If anyone does not remain in me, he is thrown out like a branch, and dries up; and such branches are gathered up and thrown into the fire, and are burned up.

Hebrews 6:4-8

6:4 For it is impossible in the case of those who have once been enlightened, tasted the heavenly gift, become partakers of the Holy Spirit, 6:5 tasted the good word of God and the miracles of the coming age, 6:6 and then have committed apostasy, to renew them again to repentance, since they are crucifying the Son of God for themselves all over again and holding him up to contempt. 6:7 For the ground that has soaked up the rain that frequently falls on it and yields useful vegetation for those who tend it receives a blessing from God. 6:8 But if it produces thorns and thistles, it is useless and about to be cursed; its fate is to be burned.

Hebrews 10:26-30

10:26 For if we deliberately keep on sinning after receiving the knowledge of the truth, no further sacrifice for sins is left for us, 10:27 but only a certain fearful expectation of judgment and a fury of fire that will consume God’s enemies. 10:28 Someone who rejected the law of Moses was put to death without mercy on the testimony of two or three witnesses. 10:29 How much greater punishment do you think that person deserves who has contempt for the Son of God, and profanes the blood of the covenant that made him holy, and insults the Spirit of grace? 10:30 For we know the one who said, “Vengeance is mine, I will repay,” and again, “The Lord will judge his people.”

Hebrews 10:39

10:39 But we are not among those who shrink back and thus perish, but are among those who have faith and preserve their souls.
