1 John 4:2-8 AMP

2 By this you may know (perceive and recognize) the Spirit of God: every spirit which acknowledges and confesses [the fact] that Jesus Christ (the Messiah) [actually] has become man and has come in the flesh is of God [has God for its source];

3 And every spirit which does not acknowledge and confess that Jesus Christ has come in the flesh [but would annul, destroy, sever, disunite Him] is not of God [does not proceed from Him]. This [nonconfession] is the [spirit] of the antichrist, [of] which you heard that it was coming, and now it is already in the world.

4 Little children, you are of God [you belong to Him] and have [already] defeated and overcome them [the agents of the antichrist], because He Who lives in you is greater (mightier) than he who is in the world.

5 They proceed from the world and are of the world; therefore it is out of the world [its whole economy morally considered] that they speak, and the world listens (pays attention) to them.

6 We are [children] of God. Whoever is learning to know God [progressively to perceive, recognize, and understand God by observation and experience, and to get an ever-clearer knowledge of Him] listens to us; and he who is not of God does not listen or pay attention to us. By this we know (recognize) the Spirit of Truth and the spirit of error.

7 Beloved, let us love one another, for love is (springs) from God; and he who loves [his fellowmen] is begotten (born) of God and is coming [progressively] to know and understand God [to perceive and recognize and get a better and clearer knowledge of Him].

8 He who does not love has not become acquainted with God [does not and never did know Him], for God is love.
