Psalm 75:7 But God is the judge: He putteth down one, and setteth up another.
So often we think that we choose things that God has chosen. It was God that chose who would be the king of Israel. It was God who chose who would be the priest. It was God who chose the tribe that would be His servants. It was God who chose Abraham, Issac, Jacob, and so on to be the leaders of His people.
God chooses. God decides. I want to serve where He has put me. He has made choices of how He wants to use me and I want to be used that way. I want to trust that He knows just where, when, and how to use me. I am His man!
