[writing about Eph 3:18-19] BREADTH, LENGTH, DEPTH, and HEIGHT...They are made use of to shew to the Ephesians, that God with what he is in himself, and with what he hath in his power, is all for the use and profit of the believers. Else no great matter is held out to them thereby. "But this God is our God!" there is the comfort: For this cause therefore he presenteth them with this description of him. To wit, by breadth, and length, and depth, and height: As who should say, the High God is yours; the God that fills heaven and earth is yours; the God whom the heaven of heavens cannot contain, is yours; yea, the God whose works are wonderful, and whose ways are past finding out, is yours. Consider therefore the greatness that is for you, that taketh part with you, and that will always come in for your help against them that contend with you. It is my support, it is my relief; it [is] my comfort in all my tribulations, and I would have it ours, and so it will when we live in the lively faith thereof. Nor should we admit of distrust in this matter from the consideration of our own unworthiness, either taken from the finiteness of our state, or the foulness of our ways (Psa 46). For now, though God's attributes, several of them in their own nature, are set against sin and sinners; yea, were we righteous, are so high that needs they must look over us, for 'tis to him a condescension to behold things in heaven: How much more then to open his eyes upon such as we: yet by the passion of Jesus Christ, they harmoniously agree in the salvation of our souls. Hence God is said to be love (1 John 4), God is love; might some say, and justice too: but his justice is turned with wisdom, power, holiness and truth, to love; yea, to love those that be found in his Son: forasmuch as there is nothing fault-worthy in his righteousness which is put upon us. So then, as there is in God's nature a length, and breadth, and depth, and height, that is beyond all that we can think: So we should conclude that all this is love to us, for Christ's sake; and then dilate with it thus in our minds, and enlarge it thus in our meditations; saying still to our low and trembling spirits: "It is high as heaven; what canst thou do? deeper than hell; what canst thou know? the measure thereof is longer than the earth, and broader than the sea" (Job 11:8,9).
