That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:
as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.
And this is the plan: At the right time he will bring everything together under the authority of Christ—everything in heaven and on earth.
