God’s all-sufficiency in himself is his absolute and
universal perfection, whereby nothing is wanting in him, nothing
to him: No accession can be made to his fulness, no decrease or
wasting can happen thereunto. There is also in him an all-sufficiency for
others; which is his power to impart and communicate his goodness and
himself so to them as to satisfy and fill them, in their utmost capacity,
with whatever is good and desirable to them. For the first of these, — his
all-sufficiency for the communication of his goodness, that is, in
the outward effect of it, — God abundantly manifested in the creation, in
that he made all things good, all things perfect; that is, to whom nothing
was wanting in their own kind; — he put a stamp of his own goodness upon
them all. But now for the latter, — his giving himself as an
all-sufficient God, to be enjoyed by the creatures, to hold out
all that is in him for the satiating and making them blessed, —
that is alone discovered by and in Christ. In him he is a Father, a God in
covenant, wherein he hath promised to lay out himself for them; in him hath
he promised to give himself into their everlasting fruition, as their
exceeding great reward.
