Hebrews 10:28 (KJV)

Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;)

And let us consider one another to provoke unto love and to good works:

Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.

For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,

But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.

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?

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.

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

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

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