1 Corinthians 3:15
15 If the work is burned up, the builder will suffer loss; the builder will be saved, but only as through fire.

1 Peter 1:7
7 so that the genuineness of your faith—being more precious than gold that, though perishable, is tested by fire—may be found to result in praise and glory and honor when Jesus Christ is revealed.

Hebrews 12:6-11
6 for the Lord disciplines those whom he loves, and chastises every child whom he accepts.” 7 Endure trials for the sake of discipline. God is treating you as children; for what child is there whom a parent does not discipline? 8 If you do not have that discipline in which all children share, then you are illegitimate and not his children. 9 Moreover, we had human parents to discipline us, and we respected them. Should we not be even more willing to be subject to the Father of spirits and live? 10 For they disciplined us for a short time as seemed best to them, but he disciplines us for our good, in order that we may share his holiness. 11 Now, discipline always seems painful rather than pleasant at the time, but later it yields the peaceful fruit of righteousness to those who have been trained by it.

Matthew 12:32
32 Whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.

1 Peter 3:19
19 in which also he went and made a proclamation to the spirits in prison,

Revelation 21:27
27 But nothing unclean will enter it, nor anyone who practices abomination or falsehood, but only those who are written in the Lamb's book of life.

Hebrews 12:23
23 and to the assembly of the firstborn who are enrolled in heaven, and to God the judge of all, and to the spirits of the righteous made perfect,

Colossians 1:24
24 I am now rejoicing in my sufferings for your sake, and in my flesh I am completing what is lacking in Christ's afflictions for the sake of his body, that is, the church.

1 John 5:14-17
14 And this is the boldness we have in him, that if we ask anything according to his will, he hears us. 15 And if we know that he hears us in whatever we ask, we know that we have obtained the requests made of him. 16 If you see your brother or sistercommitting what is not a mortal sin, you will ask, and God will give life to such a one—to those whose sin is not mortal. There is sin that is mortal; I do not say that you should pray about that. 17 All wrongdoing is sin, but there is sin that is not mortal.
