Ephesians 3:16-19 That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man; That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love, May be able to comprehend with all saints what is the breadth, and length, and depth, and height; And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.

The inner man is the dwelling place of God. He does not push you aside and occupy your inner being, He is spirit and adds that fourth dimension. It only takes three dimensions to define the limits of any object. Breadth, length and depth define you as an object, it is the height that makes you more than just an object.

John 14:23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.

2 Corinthians 3:3 Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart.

This is where your spiritual life happens, in the inner man, with Christ. To grow in Christ is to allow His presence to change the inner man, to go beyond knowledge, to be intimate in ways you cannot be with anyone else. When the inner man changes the outward expressions, the appearances, speech, communications and actions of the outer man begins to reflect the new man in Christ.

Outward and seeming, inward and real.
