Nowhere does the Bible state that the Spirit dwells personally in a Christian. The Holy Spirit dwells in God's children. To deny this is to deny plain passages of Scripture. Paul wrote, "That good thing which was committed unto thee keep by the Holy Ghost which dwelleth in us" (2 Tim. 1:14; cf. 1 Cor. 6:19; Rom. 8:9).
But the issue is not whether the Spirit dwells in us, but how does he dwells - personally or through faith?
"Let the word of Christ dwell in you richly..--Col.3:16
Do you have literal words of Christ dwelling in you?
Notice that God the Father resides in the Christian. John wrote, "God dwelleth in us" (1 Jn. 4:12; cf. vv. 13,15,16). Does God personally dwell in us? John explicitly states that God dwells in us, but I don't know of no one who says his personal Being is in us.
Jesus also dwells in us. (Gal. 2:20 and Col. 1:27 Christ dwelling in us).
"And if Christ be in you, the body is dead because of sin" (Rom. 8:10).
"But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you" (Rom. 8:9).
How can one make Christ's indwelling in Romans 8:10 representative , but make the Holy Spirit's indwelling in Romans 8:9, the verse before, personal?
"Do you not believe that I am in the Father and the Father is in me? The words that I say to you I do not speak on my own authority, but the Father who dwells in me does his works. Believe me that I am in the Father and the Father is in me.." -- John 14:10 -11
Jesus is in God and God is in Jesus. HOW? Personally? There is only one God, One Jesus, and ONE Holy Spirit.
