My times are in Your hands.

Psalm 31:15

This is a portion of a sermon by John Piper where he preached on God's sovereignty...

God the almighty reigns in all the affairs of men. He rules the nations (Daniel 2:21) and he rules families. His providence extends from the U.S. Congress to your kitchen. Let's be like the women of faith in the Old Testament. Whatever else they doubted, they never doubted that God was involved in every part of their lives and that none could stay his hand (Daniel 4:35). He gives rain and he takes rain. He gives life and he takes life. In him we live and move and have our being. Nothing—from a toothpick to the Taj Mahal—is rightly understood except in relation to God. He is the all-encompassing, all-pervading reality. Naomi was right and we should join her in this conviction. God the Almighty reigns in all the affairs of men.

A great quote(source unknown):

"The sovereignty of God means that God can do any thing He wants to do, any time He wants to do it, any way He wants to do it, for any purpose He wants to accomplish."
