1John 4:16-17 And we have known and believed the love that God has to us. God is love; and he that dwells in love dwells in God, and God in him. Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
‘God is love’ the phrase “God is love” does not constitute the being of God. It must be understood in the same sense that we understand God is light, God is good, God is a Spirit, God is a consuming fire, and other statements about Him. In the same sense, we understand that Jesus is the way, the truth, and the life, or the door (John 10:9; 14:6). These expressions don’t do away with the reality and personality of God and Christ.
‘And he that dwells in love dwells in God, and God in him’ without [agape] love we cannot be in union with God, nor can He be with us. We must have knowledge of Him – through His Word only – and then implement this knowledge in our day-to-day life so we can experience His judgement (consequences), only then will our love for Him grows (Php. 1:9).
‘Herein is our love made perfect’ by God dwelling in us, by our dwelling in Him, by having the fullness of love in our lives, and by the perfection of that love in daily manifestation, we may have boldness in the Day of Judgment. This is possible because we are like God – holy, pure, loving, good, and true – in this world (Tit. 2:11-12).
‘Day of judgment’ this is the 5th and last New Testament prophecy in 1 John. Christians will be judged at the judgment seat of Christ (1Cor. 3:11-15). Sinners will be judged at the great white throne over 1,000 years later (Rev. 20:11-15).
‘As he is’ what a rebuke to those who hold that men cannot live victorious over the world, the flesh, and the devil (Matt. 5:48; Rom. 6:14-23)!
