Hebrews 4:11

Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.

And to whom sware he that they should not enter into his rest, but to them that believed not? So we see that they could not enter in because of unbelief. Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it.

Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light.

Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall: For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ.

Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience.

And we desire that every one of you do shew the same diligence to the full assurance of hope unto the end:

Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.

Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.

They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.

Whereupon, O king Agrippa, I was not disobedient unto the heavenly vision:

For which things’ sake the wrath of God cometh on the children of disobedience:

The law and the prophets were until John: since that time the kingdom of God is preached, and every man presseth into it.

And from the days of John the Baptist until now the kingdom of heaven suffereth violence, and the violent take it by force.

Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:

For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another.

Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:

Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.

For as ye in times past have not believed God, yet have now obtained mercy through their unbelief: Even so have these also now not believed, that through your mercy they also may obtain mercy. For God hath concluded them all in unbelief, that he might have mercy upon all.
