“To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory.” (Colossians 1:27)

The fact that Jesus Christ is actually in each believer is both a great mystery and rich in glory. In fact, it is our very hope and assurance of glory in the age to come.

How Christ may be both seated at “the right hand of the Majesty on high” (Hebrews 1:3) and yet living in us is surely a mystery, yet it is fully true. He Himself told His disciples: “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....Abide in me, and I in you....He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing” (John 14:23; 15:4-5).

The apostle Paul also confirmed this great truth: “I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me” (Galatians 2:20). One of his prayers for the Ephesians was “that Christ [might] dwell in [their] hearts by faith” (Ephesians 3:17).

The mystery as to how Christ can live in us is resolved by yet another mystery—that of the triunity of the Godhead. Christ, the Second Person, is present in His people through the Holy Spirit, the Third Person. Christ said: “I will pray the Father, and he shall give you another Comforter....Even the Spirit of truth;...for he dwelleth with you, and shall be in you” (John 14:16-17).

In fact, as our text says, His indwelling presence is our very hope of glory, for “if any man have not the Spirit of Christ, he is none of his” (Romans 8:9).

Thus, where we go, He goes; whatever we say, He hears; even what we think, He knows. Christ, by the Holy Spirit, is our ever-present comforter and guide and counselor. This is, indeed, a glorious mystery! HMM
