God the Father is said to dwell in us by love. God the Father doth more eminently dwell in us by our apprehensions of him in love; both in his love to us, and our loving of him: so you will find it in 1 John iv. 16, ‘And we have known and have believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him.’ Brethren, a man that hath great apprehensions, or any true apprrehensions of the love of God to him, and his heart is kept dwelling and abiding on them, he doth thereby dwell with God the Father. If you look to the whole Scripture, the eminent property that is ascribed to the Father is love: ‘The grace of our Lord Jesus Christ, and the love of God the Father.’ Though Christ loves us too, yet it is the Father’s love is the original of all. The more you apprehend the love of the Father, whether you do it in assurance, or whether you do it in adoring that love, and cleaving to that love, and following after that love you apprehend in the Father; the more you do this, the more doth God the Father dwell in you: therefore the Apostle prayeth, ‘That Christ may dwell in your hearts by faith, that ye being rooted and ground in love:’ but it is in the love of God the Father.
From the sermon, “Christ dwelling in our hearts by faith”, from Ephesians 3:17
