Which is his body
That is, which church is the body of Christ; as an human body is but one, consisting of various members, united to each other, and set in an exact proportion and symmetry, and in a proper subservience to one another, and which must be neither more nor fewer than they are; so the church of Christ is but one general assembly, which consists of many persons, of different gifts and usefulness, and are all united together under one head, Christ, whose name they bear, and are made to drink of the same Spirit; and these are placed in such order, as throw a glory and comeliness on each other, and to be useful to one another, so that it cannot be said of the meanest member, that there is no need of it; and the number of them can neither be increased nor diminished; and this is Christ's body, his mystical body, which becomes his by the Father's gift to him, and by his own purchase; to which he is united, and of which he is the only head; and which he loves as his own body, and supplies, directs, and defends:
the fulness of him that filleth all in all;
besides the personal fulness which Christ has as God, and his fulness of ability and fitness for his work as Mediator, and his dispensatory fulness, which dwells in him for the use of his people, the church is his relative fulness, which fills him, and makes up Christ mystical; and which is filled by him, and is complete in him: and then will the church appear to be Christ's fulness, when all the elect, both Jews and Gentiles, shall be gathered in; and when these are all filled with the grace designed for them; and when they are all grown up to their full proportion, or are arrived to the measure of the stature of the fulness of Christ; which will be a glorious sight to see, and very desirable: and this shows the certainty of the saints' perseverance and salvation: for if anyone member, even the meanest, could be lost, the church would not be the fulness of Christ: and this may be further concluded, from its being his fulness, who
filleth all in all;
which may be understood either more extensively; for he fills both worlds with inhabitants; he fills all places with his omnipresence, and all creatures with proper food and sustenance: or with a limitation to the church and people of God; he fills all his churches and ordinances with his gracious presence; and he fills the various societies of his saints with members and with officers; and these with the gifts and graces of his Spirit, suitable to their place and station; he fills all and every of the saints, all the vessels of mercy, whether greater or lesser, all sorts of them, of larger or meaner capacities; he fills all the powers and faculties of their souls, their hearts with joy, their minds with knowledge, their consciences with peace, their wills with spiritual desires, submission and resignation, and their affections with love to himself and people: in short, he fills them with all grace and goodness, and the fruits of righteousness; and so makes them meet for usefulness here, and for happiness hereafter; the fulness of the earth in ( Psalms 24:1 ) is by the Jews interpreted of the souls of the righteous, and of the congregation of Israel F8.
