But Moses answered, “You know that I am such a poor speaker; why should the king listen to me?” The Lord said, “I am going to make you like God to the king, and your brother Aaron will speak to him as your prophet. Exodus 6:30 – 7:1
Hard times are the ones that allow us to grow and mature while we learn what our weaknesses are. Most of them are unknown even to us, for we were born with them or acquired them during the course of life. Without realizing it, they are part of us.
Weaknesses are what make us fail and they stop us from taking responsibility for our faults or the mistakes we make. The man of God must be concerned about knowing himself better and having knowledge of which those weaknesses are. He who does not know himself does not know what he is good for or not, what he wants or not. That is why he becomes prisoner of weaknesses, for he does not know how to go about crises, so he loses what he could have attained because he never worked on the areas he should have strengthened.
God told Moses to go to Pharaoh and appear before him. The battle Moses had was very hard. He knew it was God asking him. That moment made him face his weakness, so he acknowledged his limitation. Said limitation made Moses not talk to Pharaoh, but Aaron did. God knew about the condition Moses had, yet He did not take it from him, for He wants us to overcome each one and not make excuses when the time comes to do his work.
