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.

31 It is a fearful thing to fall into the hands of the living God.

32 But call to remembrance the former days, in which, after ye were illuminated, ye endured a great fight of afflictions;

33 Partly, whilst ye were made a gazingstock both by reproaches and afflictions; and partly, whilst ye became companions of them that were so used.

34 For ye had compassion of me in my bonds, and took joyfully the spoiling of your goods, knowing in yourselves that ye have in heaven a better and an enduring substance.

35 Cast not away therefore your confidence, which hath great recompence of reward.

36 For ye have need of patience, that, after ye have done the will of God, ye might receive the promise.

37 For yet a little while, and he that shall come will come, and will not tarry.

38 Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.

39 But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.

Hebrews 11:1
11 Now faith is the substance of things hoped for, the evidence of things not seen.

Romans 12:19
19 Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.
