And we have seen and testify that the Father sent his Son to be the Savior of the world.
In context
12No one has ever seen God. But if we love one another, God remains in us, and his love is made complete in us. 13This is how we know that we remain in him and he in us: he has given us of his Spirit. 14And we have seen and testify that the Father sent his Son to be the Savior of the world. 15Whoever confesses that Jesus Christ is the Son of God, God remains in him, and he in God. 16And we have come to know and to believe the love that God has for us. God is love, and whoever remains in love remains in God, and God remains in him.
