The rain comes down

The rain comes down and cleans the ground and the air, washing the impurities away. Carrying them into the ground where what is impure causes plants to grow and food to germinate.
Then once again, the cycle repeats itself, the perfect system.
Yet those that doubt God do not see His hand in it. A system designed to promote life, a system that feeds off each other.
We breathe in oxygen and nitrogen and exhale carbon dioxide, which feeds the trees and causes it to grow and release oxygen into the air. Tet there are those that do not see within it the hand of God.
God who created everything you see and you yourself. Yet there are those that do not see God.
