Man's tendency is to limit himself to past experiences and not take on challenges that will stretch his abilities. We often say "No" to challenges that we know we should accept because it might take us beyond our comfort zone.

Though Moses was once a prince of Egypt, forty years of being a shepherd gave him a tranquil life and he liked it. There was a second experience that he could recall of brothers and sisters, and fellow Hebrews in slavery in Egypt. With all the tranquility of being a shepherd, he could not forget the picture of the mistreatment of his people in Egypt. Therefore, when God caught his attention, he identified himself as being the "god of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob." God then made him aware that he was acquainted with the misery of his people in Egypt, and that he was ready to do something about it.

Moses could agree that it was time that God should make some move to help his people, but he could not agree that he was to be the one God would send to do it. His first question was, "Who am I that I should go before Pharaoh?" No greater assurance could God give Moses than to say, "I will be with you."

Moses could think only of his inadequacies and not that he was an instrument of God to do his work. He was given all kinds of assurances such as his shepherd's staff becoming a snake, and his hand becoming leprous and then cleansed again, but Moses still found reasons not to go to Egypt, by saying, "I am not a speaker…."

God responded by asking, "Who made man's mouth?" and even assured him that Aaron, his brother was on his way to meet him and be his speaker. After all of these assurances, Moses still tried to beg off. God became angry.

If you want to make God angry, keep making excuses.
