And we ourselves know and believe the love which God has for us. God is love, and those who live in love live in union with God and God lives in union with them.
However, as the scripture says, “What no one ever saw or heard, what no one ever thought could happen, is the very thing God prepared for those who love him.”
See how much the Father has loved us! His love is so great that we are called God's children—and so, in fact, we are. This is why the world does not know us: it has not known God.
Those who obey God's commands live in union with God and God lives in union with them. And because of the Spirit that God has given us we know that God lives in union with us.
