Be humble and courage to serve the Lord

Exodus 4:1-31
God gave a few signs to Moses, let him may express to others. People will know the Lord do have appeared to him.
Moses said he is slow of speech and tongue. The Lord said to him, "Who gave man his mouth? Who makes him deaf or mute? Who gives him sight or makes him blind? Is is not I, the Lord" Now go; I will help you speak and will teach you what to say."
But Moses said, "O Lord, please send someone else to do it." Then the Lord's anger burned against Moses and he said, "What about your brother, Aaron the Levite? I will help both of you speak and will teach you what to do."
The Lord told Moses the Pharaoh will not listen to him, and God will kill their firstborn son, then they will let him go.
Before serve the Lord, Moses need circumcision, so his wife Zipporah took a flint knife, cut off her son's foreskin and touched Moses's feet with it.
The people won't believe me, God gives Moses three sings with which to convince them that he really has met with God. This is the kind of magic they are familiar with: the kind that went with the religion of Egypt.
'I am no speaker', 'But God who made him will enable Moses to speak.
'Please send someone else',. This God will not do, but Moses is allowed his brother Aaron as spokesman.
Why?
Moses had not any faith to do this mission - bring Israelite out from Egypt, so he wanted many miracle signs and he said he is slow to speak.
God will help his servant to speak and to do the miracle things. Do not afraid. God like our humble before him.
How?
Be humble and be courage to serve the Lord, I am not along, God always be with me.
