he should
John 15:4-6
4
Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.
5
I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.
6
If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.
Acts 11:23
Who, when he came, and had seen the grace of God, was glad, and exhorted them all, that with purpose of heart they would cleave unto the Lord.
Acts 27:31
Paul said to the centurion and to the soldiers, Except these abide in the ship, ye cannot be saved.
Hebrews 3:14
For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;
Hebrews 6:4-8
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.
7
For the earth which drinketh in the rain that cometh oft upon it, and bringeth forth herbs meet for them by whom it is dressed, receiveth blessing from God:
8
But that which beareth thorns and briers is rejected, and is nigh unto cursing; whose end is to be burned.
Hebrews 10:26-30
26
For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
27
But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
28
He that despised Moses' law died without mercy under two or three witnesses:
29
Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?
30
For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people.
Hebrews 10:39-30
after the death
Hebrews 9:11
But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building;
Hebrews 9:12
Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
Hebrews 9:15-17
15
And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
16
For where a testament is, there must also of necessity be the death of the testator.
17
For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
