In Psalm 19:1. David said, "The heavens are telling of the glory of God; And their expanse is declaring the work of His hands." (NASB) Another passage that testifies to God's kindness is the whole chapter of Psalm 104.

Nature tells us not only the existence of God, but also some things about Him. He is kind, compassionate, merciful and he loves his creatures. God is not chaotic; he is a God of order and law. He gives to us all that is good. You know that if you plant a seed and do your part to care for it, you will have a harvest (a return).

What makes crops to grow? Why the seasons? Why air pressure, evaporation and precipitation, that is, why rain on the earth? The bible teaches that God made and created all these things (Genesis 1:1). The Bible also says that God maintains this creation (Hebrews 1:1-3). The design of a creation which supports what we call living entities (creatures) is reasonable. Life begets life; but can life come from nothing? Logic would dictate, nothing comes from nothing. Therefore, I conclude that reason and logic points to a designer, creator and maintainer of this physical universe. I do concede it is a matter of faith that there is an invisible God. He can't be shown in a test tube. But the earth and the universe testifies, tells us or speaks to us that there is God and He is good. He is responsible for His creation and because of His loving-kindness, He provides for us.
