1 John 5:16-19

King James Version

¹⁶ If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.

¹⁷ All unrighteousness is sin: and there is a sin not unto death.

¹⁸ We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.

¹⁹ And we know that we are of God, and the whole world lieth in wickedness.
