1 John 4:15-18World English Bible (WEB)
15 Whoever confesses that Jesus is the Son of God, God remains in him, and he in God. 16 We know and have believed the love which God has for us. God is love, and he who remains in love remains in God, and God remains in him. 17 In this love has been made perfect among us, that we may have boldness in the day of judgment, because as he is, even so are we in this world. 18 There is no fear in love; but perfect love casts out fear, because fear has punishment. He who fears is not made perfect in love.
1 John 4:15-18Amplified Bible, Classic Edition (AMPC)
15 Anyone who confesses (acknowledges, owns) that Jesus is the Son of God, God abides (lives, makes His home) in him and he [abides, lives, makes his home] in God.
16 And we know (understand, recognize, are conscious of, by observation and by experience) and believe (adhere to and put faith in and rely on) the love God cherishes for us. God is love, and he who dwells and continues in love dwells and continues in God, and God dwells and continues in him.
17 In this [union and communion with Him] love is brought to completion and attains perfection with us, that we may have confidence for the day of judgment [with assurance and boldness to face Him], because as He is, so are we in this world.
18 There is no fear in love [dread does not exist], but full-grown (complete, perfect) love [a]turns fear out of doors and expels every trace of terror! For fear [b]brings with it the thought of punishment, and [so] he who is afraid has not reached the full maturity of love [is not yet grown into love’s complete perfection].
