And there are three that bear testimony on earth, the spirit, and the water, and the blood: and these three agree in one.
If we receive the testimony of men, the testimony of God is greater: for this is the testimony of God which he hath testified of his Son.
He that believeth on the Son of God hath the witness in himself: he that believeth not God, hath made him a liar, because he hath not believed the testimony that God gave of his Son.
And this is the testimony, that God hath given to us eternal life: and this life is in his Son.
He that hath the Son, hath life; [and] he that hath not the Son of God, hath not life.
These things have I written to you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
And this is the confidence that we have in him, that if we ask any thing according to his will, he heareth us:
And if we know that he heareth us, whatever we ask, we know that we have the petitions that we desired from him.
If any man shall see his brother sin a sin [which is] not to death, he shall ask, and he will give him life for them that sin not to death. There is a sin to death: I do not say that he shall pray for it.
All unrighteousness is sin: and there is a sin not to death.
We know that whoever is born of God, sinneth not; but he that is begotten of God, keepeth himself, and that wicked one toucheth him not.
