…consider Romans 8:10 (KJV), which says, “If Christ is in you, the body is dead because of sin.” Or consider Galatians 2:20, “Christ lives in me.” It is clear in these verses that if the Spirit is in us, then Christ is in us. Christ dwells in our hearts by faith. But the Holy Spirit is the person of the Trinity who actually dwells in us, having been sent by the Son who has gone away but who will come again in person when we shall literally see Him.
