“Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.”
King James Version (KJV)
3:15 He, I say, abideth in spiritual death, is void of the life of God. For whosoever hateth his brother, and there is no medium between loving and hating him, is, in God's account, a murderer: every degree of hatred being a degree of the same temper which moved Cain to murder his brother. And no murderer hath eternal life abiding in him - But every loving believer hath. For love is the beginning of eternal life. It is the same, in substance, with glory.
1Jo 3:15 Whosoever hateth his brother is a murderer. Has the germs from which murder springs lurking in his heart. Hatred led Cain to murder; so it does many other who sin likewise. And ye know that no murderer hath eternal life abiding in him. It is impossible for a man to have the spirit of murder in him and yet have eternal life.
