11 Dear friends, if God loved us in this way, we also must love one another.w 12 No one has ever seen God.x If we love one another, God remains inD us and his love is made complete in us. 13 This is how we know that we remain in himy and he in us: He has given us of his Spirit.z 14 And we have seen and we testify that the Father has sent his Sonaa as the world’s Savior. 15 Whoever confessesab that Jesus is the Son of God—God remains in him and he in God.
