He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
He that believeth on him is not condemned, х ou (G3756) krinetai (G2919)] - literally, 'is not being judged,' or 'is not coming into judgment.' The meaning is, as the apostle expresses it, that "there is now no condemnation to them which are in Christ Jesus" (Romans 8:1). Compare John 5:24, "He that heareth my word, and believeth on Him that sent me hath everlasting life, and shall not come into condemnation, but is (or hath) passed from death unto life."
But he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. Rejecting the one way of deliverance from that condemnation which God gave His Son to remove, they thus willfully remain condemned.
