song of moses
Listen, O heavens, and I will speak; hear, O earth, the words of my mouth.
Let my teaching fall like rain and my words descend like dew, like showers on new grass, like abundant rain on tender plants.
I will proclaim the name of the Lord.
Oh, praise the greatness of our God!
He is the Rock, his works are perfect, and all his ways are just.
Deuteronomy 32:1-3

The works of God are perfect.
An understanding of the things of God from his Word is like light rain causing new life to spring forth in the dry wasteland.
