1 John 4:2-4

Young's Literal Translation

² in this know ye the Spirit of God; every spirit that doth confess Jesus Christ in the flesh having come, of God it is,

³ and every spirit that doth not confess Jesus Christ in the flesh having come, of God it is not; and this is that of the antichrist, which ye heard that it doth come, and now in the world it is already.

⁴ Ye -- of God ye are, little children, and ye have overcome them; because greater is He who [is] in you, than he who is in the world.
