When God called Moses in the burning bush for the assignment of leading the people of Israel out of Egypt:
God did not speak to the people of Israel about Moses' coming to liberate them
God did not speak to Pharaoh about Moses' assignment, on the contrary He hardened his heart.
Moses had to use the power that was bestowed in him by God to convince both Pharaoh and the people of Israel that he was sent by God.
We each have a position in the Body of Christ and a distinct mission to fulfill.. and God has perfectly equipped us to succeed in His assignment.
People around you may not believe in your assignment, its up to you to use the power that God has bestowed in you in you to convince them that you are truly on God's assignment.
