When someone like Moses demonstrates self doubt, it shows that we are dealing with a man. That’s the beauty of scripture. We can see ourselves in the characters. Now Moses is really uncertain whether he should do the work. So he went back to his old excuse: I am of uncircumcised lips. The irony is that he is talking to God. When self doubts become debilitating, we need help. Self doubts occur when we lack confidence to do what is necessary in life. There’s the feeling that we are not good enough. Self doubt does not operate by faith. Its a panic that may accompany promotion. Experts say several factors ranging from childhood upbringing, fear, comparison to others or just the prospect of a new project may cause self doubts. Moses had failed before in helping to rescue an Israelite. Now he is wondering what may happen again. The truth is that God behaves as if He is not aware of all these researches. He gives the instructions again. God knows that in this world we have to accomplish in spite of how we feel. One thing to do is to understand that any negative thinking that contradicts God’s instruction is from the devil. The essence is to keep you bound. So God kept giving him validation to make Moses see. If you are experiencing this, look for the word of God. With God, all things are possible.
And Moses said before the Lord, Behold, I am of uncircumcised lips, and how shall Pharaoh hearken unto me? Exodus 6:30 KJV
