Exodus 3:10

Come now, therefore, and I will send thee unto Pharaoh, that thou mayest bring forth My people, the children of Israel, out of Egypt. This was the object of the Lord's explanation, to make Moses the leader of the people in effecting their deliverance from the bondage of Egypt. With. out the command and call of God no man should venture to undertake work in His kingdom. Even Christ glorified not Himself to be made a High Priest, Hebrews 5:5. Moses received an immediate call from God; His method at the present time is that of the mediate call, through the congregations or their representatives.
