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].
We love Him, because He first loved us.
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.
And this command (charge, order, injunction) we have from Him: that he who loves God shall love his brother [believer] also.
