God's 2nd book, nature, teaches us spiritual lessons. For example, as the white snow covers the earth, so too can your sins be covered by His white robe of righteousness.
Come now, and let us reason together,
Come now, and let us reason together,
saith the LORD:
though your sins be as scarlet,
they shall be as white as snow;
though they be red like crimson,
they shall be as wool.
Isaiah 1:18
