How Can we not Believe.

I recieved the below email devotional today and want to share it with you as it does talk about the beauties that surround us in nature and truly there must be a God who would craft such an awsome world, the beauties of nature and the circle of life.... how can we not believe.

There are things about him that people cannot see. ... But since the beginning of the world those things have been made easy to understand by what God has made. ROMANS 1:20

God's judgment [on the day Christ returns] is based upon humanity's response to the message received. He will never hold us accountable for what he doesn't tell us. At the same time, he will never let us die without telling us something. Even those who never heard of Christ are given a message about the character of God. "The heavens declare the glory of God" (Ps. 19:1 NIV)....
Nature is God's first missionary. Where there is no Bible, there are sparkling stars. Where there are no preachers, there are springtimes.... If a person has nothing but nature, then nature is enough to reveal something about God. As Paul says...: "God's law is not something alien, imposed on us from without, but woven into the very fabric of our creation. There is something deep within [people] that echoes God's yes and no, right and wrong. Their response to God's yes and no will become public knowledge on the day God makes his final decision about every man and woman" (Rom. 2:15-16 MSG).
