We love because he first loved us.
In context
17This is how love is made complete among us, so that we may have confidence on the day of judgment: because as he is, so are we in this world. 18There is no fear in love. But perfect love drives out fear, because fear has to do with punishment, and whoever fears has not been made complete in love. 19We love because he first loved us. 20If anyone says, “I love God,” yet hates his brother or sister, he is a liar. For whoever does not love his brother or sister, whom he has seen, cannot love God, whom he has not seen. 21And he has given us this command: whoever loves God must also love his brother or sister.
