Psalm 19: 1 says, “The heavens declare the glory of God, and the sky above proclaims his handiwork.” These verses clearly show that God reveals his attributes through nature. We can see in creation the greatness and beauty of God. All who love mountains and waterfalls and oceans, all who climb and dive and photograph the wonders of nature, all who love animals — even if these people attribute these things entirely to natural causes — see God. This is the natural bridge to theism, a belief in God. It is not the gospel, but it can prepare people to hear it.
