Hebrews 12:15

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

Lest there should be among you man, or woman, or family, or tribe, whose heart turneth away this day from the LORD our God, to go and serve the gods of these nations; lest there should be among you a root that beareth gall and wormwood;

Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.

We then, as workers together with him, beseech you also that ye receive not the grace of God in vain.

Be not deceived: evil communications corrupt good manners.

Yet I had planted thee a noble vine, wholly a right seed: how then art thou turned into the degenerate plant of a strange vine unto me?

Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?

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.

Keep thy heart with all diligence; for out of it are the issues of life.

Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless.

Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.

Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?

Wherefore let him that thinketh he standeth take heed lest he fall.

And he shall give Israel up because of the sins of Jeroboam, who did sin, and who made Israel to sin.

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

Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons’ sons;

For their vine is of the vine of Sodom, and of the fields of Gomorrah: their grapes are grapes of gall, their clusters are bitter:

Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.

Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry:

And Moses said unto Aaron, What did this people unto thee, that thou hast brought so great a sin upon them?
