1 Cor 16:14 (AMP)Let everything you do be done in love (true love to God and man as inspired by God’s love for us).
Everything? That's what God wants from us. And the only way we can even begin to carry out such a command, is to get close to God and understand His great love for us. "We love Him because He first loved us" (1 John 4:19).
The closer we draw to God, the easier it becomes to do everything in love, because God is Love. As we do everything in love, our relationships change, we walk differently, we talk differently, and we enter into a new level of joy and peace.
