Isaiah 45:8

Drop down, ye heavens, from above, in fertilizing rain, and let the skies, the clouds of the firmament, pour down righteousness, the fullness of spiritual salvation. Let the earth open and let them bring forth salvation, that coming down from above being eagerly received by the earth, and let righteousness spring up together, in luxuriant growth; I, the Lord, have created it. The reference is to faith and its fruits as brought forth under the influence of the Word of God's grace and mercy, especially in Messianic times the ideal condition in the world. But Israel, full of doubt and mistrust on account of the misery of its captivity, murmured against God in spite of His promise of deliverance. This attitude the Lord takes into account in this section.
