The mystery is revealed, Paul certifies in his epistle to the Corinthians. For this Paul strives according to God’s mighty working in him that every man shall reach full assurance of understanding, to the acknowledgement of the mystery of God, and of the Father, and of Christ. Having full understanding of the mystery is crucial if you are to understand yourself, Paul persists. Then Paul says a most curious thing; For in him dwelleth all the fulness of the Godhead bodily. We would have assumed that Paul would have written that the fullness of the Godhead dwells spiritually since Christ is ascended. But no! Paul says bodily. The implications of what he is saying are so stunning and startling that it doesn’t immediately dawn upon us that this argument is a continuation of Christ in you. Can you imagine such a thing? The fullness of God dwelling in you! God has Himself answered His own prayer about oneness in John 17, and filled you to the rim with the fullness of Himself. Fullness means nothing left out. The Trinity again and again stoops down to fill human beings with its fullness in the similitude of Jesus. It is the creator of the universe who has personally stepped down to wholly participate in our lives with everything He is. He who said about Himself: I am that I am! He joining Himself without reservations to us is the foundation for us knowing God.
“But to know God is to be one in His oneness. The total is “one.” He and I are one. One person? Yes. One heart? Yes. One mind? Yes. One Spirit? Yes. One intent? Yes. One will? Yes. One everything? YES! Jesus has brought us, through His intercession, into the same oneness He describes with the Father and the Spirit. (John 17:21-23). This is not something to “understand” intellectually. It cannot make sense that way. It is a “BE” thing. As He is, so are we in this world.” (Fred Pruitt)
