Colossians 2:7, 9-10

having been deeply rooted [in Him] and now being continually built up in Him and [becoming increasingly more] established in your faith, just as you were taught, and overflowing in it with gratitude.

For in Him all the fullness of Deity (the Godhead) dwells in bodily form [completely expressing the divine essence of God]. And in Him you have been made complete [achieving spiritual stature through Christ], and He is the head over all rule and authority [of every angelic and earthly power].
