If you see any brother or sister commit a sin that does not lead to death, you should pray and God will give them life. I refer to those whose sin does not lead to death. There is a sin that leads to death. I am not saying that you should pray about that.
NIV
If anyone sees his brother [believer] committing a sin that does not [lead to] death (the extinguishing of life), he will pray and [God] will give him life [yes, He will grant life to all those whose sin is not one leading to death]. There is a sin [that leads] to death; I do not say that one should pray for that.
AMP
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.
KJV
We know that anyone born of God does not continue to sin; the One who was born of God keeps them safe, and the evil one cannot harm them.
NIV
We know [absolutely] that anyone born of God does not [deliberately and knowingly] practice committing sin, but the One Who was begotten of God carefully watches over and protects him [Christ's divine presence within him preserves him against the evil], and the wicked one does not lay hold (get a grip) on him or touch [him].
AMP
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.
KJV
And if we know that he hears us – whatever we ask – we know that we have what we asked of him.
NIV

AMP
And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
KJV
Who is it that overcomes the world? Only the one who believes that Jesus is the Son of God.
NIV
Who is it that is victorious over [that conquers] the world but he who believes that Jesus is the Son of God [who adheres to, trusts in, and relies on that fact]?
AMP
Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
KJV
Whoever believes in the Son of God accepts this testimony. Whoever does not believe God has made him out to be a liar, because they have not believed the testimony God has given about his Son.
NIV
He who believes in the Son of God [who adheres to, trusts in, and relies on Him] has the testimony [possesses this divine attestation] within himself. He who does not believe God [in this way] has made Him out to be and represented Him as a liar, because he has not believed (put his faith in, adhered to, and relied on) the evidence (the testimony) that God has borne regarding His Son.
AMP
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 believeth not the record that God gave of his Son.

AMP

KJV
We accept human testimony, but God's testimony is greater because it is the testimony of God, which he has given about his Son.

AMP
If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.
