Exodus 3: 10-12
Now go, and I will send you to Pharaoh, and you will bring my people the children of Israel out of Egypt.
Moses said goodbye: Who am I to go to Pharaoh, and to bring the children of Israel out of Egypt?
God said: I will be with you; and this will be a sign to you that it is I who sent you: when you bring the people out of Egypt, you will serve God on this mountain.
Let God use you for his ministry, to save souls, to help other people, do not resist any longer because there are more blessings in the service of God.
