Hebrews 6:4-8
4
For in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit,
5
and have tasted the good word of God and the powers of the age to come,

For ground that drinks the rain which often falls on it and brings forth vegetation useful to those for whose sake it is also tilled, receives a blessing from God;

Hebrews 10:26-31

27
but a terrifying expectation of judgment and THE FURY OF A FIRE WHICH WILL CONSUME THE ADVERSARIES.

How much severer punishment do you think he will deserve who has trampled under foot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace?
30
For we know Him who said, "VENGEANCE IS MINE, I WILL REPAY." And again, "THE LORD WILL JUDGE HIS PEOPLE."
31
It is a terrifying thing to fall into the hands of the living God.
1 John 5:16
If anyone sees his brother committing a sin not [leading] to death, he shall ask and [God] will for him give life to those who commit sin not [leading] to death. There is a sin [leading] to death; I do not say that he should make request for this.
