Sinclair Ferguson, A Heart for God, 1987, p. 21-22
Unless God is our Father, we are orphans. But God’s own Son has become our Older Brother. He comes through His Spirit, with His Father, to live with us. The Holy Spirit dwells in our lives, making us a suitable dwelling place to receive the Father and the Son! As a consequence, by the Spirit we learn that we are not abandoned and unloved, but rather that we are loved by the Father, by the Son, and lovingly cared for by the Holy Spirit (John 14:21).
