In studying more of the life of Moses, I had questioned why he seemed afraid and intimidated by Pharaoh. After all, he was raised among royalty after being found by Pharaoh's daughter floating in the Nile.
God told Moses in Exodus 6:11, "Go, tell Pharaoh king of Egypt to let the Israelites go out of his country." But Moses said to the Lord in verse 12, "If the Israelites will not listen to me, why would Pharaoh listen to me..?"
I believe the reason why Moses felt like he could speak to Israel, and not to Pharaoh, was because they all were slaves together. Slavery was comfortable to Moses; it was his arena and something he could handle.
Moses had a slave mentality. The Israelites were on the same level as he. But when the children of Israel didn't agree with him in Exodus 6:9, it brought back the spirit of intimidation to him. Rejection is always linked or connected to intimidation. The reason why Moses couldn't do the big things for God was because in his mind, he was little. Having a spirit of intimidation creates positions God never ordained. God had ordained Moses to tell Pharaoh to let Israel go, but Aaron had to do it. Moses' destiny was to be a deliverer, but he was so fearful in himself.
Whatever God puts in your heart to do, you have to be completely dependent upon Him. If not, YOU are confident in yourself and not God.
