Psalm 135: 7 He causes the vapors to ascend from the ends of the earth; He makes lightning for the rain; He brings the wind out of His treasuries.
The penman for this Psalm, possibly Moses, writes of the rain cycle given by God for the benefit of the land. The moisture condenses into clouds, where upon rain is released. The rain causes growth, refreshment and hope.
It also could be called the praise cycle. As our praises ascend into the atmosphere, the Lord gathers them and then releases them back to us with His presence that bring growth, refreshment and hope.
When we crave Him, His presence; initiate the praise cycle. He’ll rain down Himself!
