A. W. Tozer 
Man-The Dwelling Place of God [EPUB ebook] 

At the hidden center of man’s being is the dwelling place of the Triune God.  It is such a private, intimate place that no one can intrude but Christ, and even He will enter only through an invitation of faith. Once the Spirit enters the core of the believer’s heart and establishes residence there, man becomes a true child of God. But baptism, confirmation, receiving the sacraments, church membership, etc., mean nothing unless God has truly inhabited the soul.

In Man: The Dwelling Place of God, Tozer reveals what it truly means to have Christ within us—like leaving your old life behind,  understanding the Bible, making godly choices, loving God for Himself, Christian fellowship, and more.
