14 And [besides] we ourselves have seen (have deliberately and steadfastly contemplated) and bear witness that the Father has sent the Son [as the] Savior of the world.
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 turns fear out of doors and expels every trace of terror! For fear 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].
19 We love Him, because He first loved us.
20 If anyone says, I love God, and hates (detests, abominates) his brother [in Christ], he is a liar; for he who does not love his brother, whom he has seen, cannot love God, Whom he has not seen.
