For just as rain and snow fall from heaven and do not return without watering the earth, making it bud and sprout, and providing seed to sow and food to eat,
We have here a further account of that covenant of grace which is made with us in Jesus Christ, both what is required and what is promised in the covenant, and of those considerations that are sufficient abundantly to confirm our believing compliance with and reliance on that covenant.
Commenting on Isaiah 55:6-13
For as the rain cometh down, and the snow from heaven, and returneth not thither,.... Rain and snow come down from the clouds in the heavens, and do not return again until they have done what they are sent to do, or have produced the following effects; otherwise they may be exhaled into vapours, as they often are, and drawn up again by the sun...
The hearts of men, once barren of spirituality, shall be made, by the outpouring of the Spirit under Messiah, to bear fruits of righteousness (Isa 5:6; Deu 32:2; Sa2 23:4; Psa 72:6). snow--which covers plants from frost in winter; and, when melted in spring, waters the earth. returneth not--void; as in Isa 55:11; it returns not in the same shape, or without "accomplishing" the desired end. bud--germinate.
