Exodus 4:10 says, And Moses said unto the LORD, O my Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I am slow of speech, and of a slow tongue.  Moses offered another excuse.  We too often want to offer excuses why we cannot do what God has called us to do, seeing our limitations instead of God's power.  Moses said that he was not eloquent and was slow of speech and tongue before God called him and was still that way.  Even if God does not change what we see as a disqualifying reason to not do what He has called us to do, He will still enable us to do it.  Verse eleven declares, And the LORD said unto him, Who hath made man’s mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD?  God called Moses to make a decision about Who God really is.  God asked Moses Who had created the mouth and given people the ability to speak and even the ability to see.  I believe that once we acknowledge God as the Creator and Sustainer of the universe, that we should have no reason to question Him when He calls us to do anything, no matter how impossible we may feel it to be.  Verse twelve adds, Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.  After reminding Moses that He was the Creator of all, God then told him to go and that He would be with his mouth and teach him what to say.  All Moses was required to do was to go in obedience.  All we are required to do today when God calls us to do something is to go in obedience.  God will empower us.  Verse thirteen says, And he said, O my Lord, send, I pray thee, by the hand of him whom thou wilt send.  Moses was still asking God to send someone else.  With God's assurance that He will be with us and empower us to do what He calls us to do, do we still ask Him to send someone else?  Verse fourteen declares, And the anger of the LORD was kindled against Moses, and he said, Is not Aaron the Levite thy brother? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart.  God became angry or upset at Moses' continued excuses and refusal.  I believe that we too can try the patience of God if we continue to offer excuses instead of obeying His call, especially if we are followers of Christ.  God offered Moses a way around his objections.  Aaron, Moses' brother was coming and he could speak well and would be glad to see Moses.  Though if Moses had had enough faith in God he could have done what God called him to do alone, God was willing to send Aaron with him to help.  If God calls us to do something, we should not need to have someone else with us before we do it.  Verse fifteen adds, And thou shalt speak unto him, and put words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do.  God said He would give Moses the words to say and Moses could tell Aaron what God said and speak to the people.  Though this was an unnecessary step, God was willing to do it help Moses.  Verse sixteen adds, And he shall be thy spokesman unto the people: and he shall be, even he shall be to thee instead of a mouth, and thou shalt be to him instead of God.  Basically, God said that Aaron would be the spokesman but hat Moses would receive the word from God.  We really should never need someone else to proclaim God's word for us.  Verse seventeen continues, And thou shalt take this rod in thine hand, wherewith thou shalt do signs.  God said that Moses would still be the one to perform the signs when they were needed.  God had not changed His call for Moses to be His spokesman, but had only accommodated his excuses.  If God calls a person for a purpose today, then that person is the best person to fulfill that calling.  Verse eighteen states, And Moses went and returned to Jethro his father in law, and said unto him, Let me go, I pray thee, and return unto my brethren which are in Egypt, and see whether they be yet alive. And Jethro said to Moses, Go in peace.  Moses went to his father-in-law, Jethro and asked his permission to leave.  This was a respectful thing to do, and Jethro told Moses to go in peace.  Even if Jethro had said no, Moses would still have had to go. It is always nice if we have our family's blessing when we go to follow God's calling, but even if we don't we must still do what God calls us to do.
