Shower, O heavens, from above,and let the clouds rain down righteousness.
Let the earth open, that salvation and righteousness may bear fruit;
let the earth cause them both to sprout;
I, the LORD, have created it.
(Isaiah 45:8 ESV)
In His goodness and sovereign power God ordains that righteousness and salvation should shower down from heaven and that the earth be receptive and burst forth with the fruit of righteousness.
Jesus is the salvation and righteousness from heaven, we are made from the dust of the earth and are called to bear fruit.
(See Genesis 2:7, Romans 3:22 and John 15:8).
