1 John 5 (KJV)

7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.

8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.

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.
