We need rain from Heaven. I like the imagery found in verse 14.
13 But the Lord made the earth by his power,
and he preserves it by his wisdom.
With his own understanding
he stretched out the heavens.
13 When he speaks in the thunder,
the heavens roar with rain.
He causes the clouds to rise over the earth.
He sends the lightning with the rain
and releases the wind from his storehouses.
