In Christ all the fullness of the Deity lives in bodily form, and in Christ you have been brought to fullness. You are not half full. Not almost enough. You are complete, in Christ.
Many live as if they were missing something essential. But Paul says: In Christ you have fullness. You need no additions, no extra rules, no religious performance. What God is dwells in Christ, and in Christ you are complete.
Today you can stop searching for what you have long had.
