Exodus 4:12 Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.
Moses obeyed God and went before Pharaoh, God was with him instructing him along the way.
Jesus has also commanded us to go, and he said that he would teach us what to say.
We have a much greater mission than Moses, yet many Christians are reluctant to obey Jesus command to go into all the world and become a witness for him.
They fail to understand that God has more at stake on our mission than on Moses's.
Please come over into this world and help us to reach the lost. He commanded us to go and, his spirit will teach us. We might be at a loss for words but he never will.
