“For in him dwelleth all the fulnesse of the Godhead bodily.”
1611 King James Version (KJV)
2:9 For in him dwelleth - Inhabiteth, continually abideth, all the fulness of the Godhead. Believers are filled with all the fulness of God, #Eph 3:19|. But in Christ dwelleth all the fulness of the Godhead; the most full Godhead; not only divine powers, but divine nature, #Col 1:19|. Bodily - Personally, really, substantially. The very substance of God, if one might so speak, dwells in Christ in the most full sense.
Col 2:9 For in him dwelleth all the fulness of the Godhead fully. You must not be drawn from Christ. He is all in all. In him is the divine fullness (all divine power). In him as revealed was God in bodily form. Compare Joh 1:14.
