God uses the most simplest of things to reveal himself, to those looking.
Example he uses nature the rainbows and the storms, the waterfalls.
He uses the seasons to reveal himself like the seasons in a mans life.
Spring is when you were born and child till you grow up into adult.
The summer season is when you are young adult till middle age in life.
Fall season is when you are middle age until you hit becoming elderly in life.
Winter season is when you are elderly until Christ takes you home after death,
So just like the seasons in a year they were created after the seasons in our lives.
