This is how we know we’re living steadily and deeply in him, and he in us: He’s given us life from his life, from his very own Spirit. Also, we’ve seen for ourselves and continue to state openly that the Father sent his Son as Savior of the world. Everyone who confesses that Jesus is God’s Son participates continuously in an intimate relationship with God. We know it so well, we’ve embraced it heart and soul, this love that comes from God.
God is love. When we take up permanent residence in a life of love, we live in God and God lives in us. This way, love has the run of the house, becomes at home and mature in us, so that we’re free of worry on Judgment Day—our standing in the world is identical with Christ’s. There is no room in love for fear. Well-formed love banishes fear. Since fear is crippling, a fearful life—fear of death, fear of judgment—is one not yet fully formed in love.
We, though, are going to love—love and be loved. First we were loved, now we love. He loved us first.
If anyone boasts, “I love God,” and goes right on hating his brother or sister, thinking nothing of it, he is a liar. If he won’t love the person he can see, how can he love the God he can’t see? The command we have from Christ is blunt: Loving God includes loving people. You’ve got to love both.
