EXODUS 5: 20 -23
And they met Moses and Aaron, who stood in the way, as they came forth from Pharaoh:
And they said unto them, the Lord look upon you, and judge; because ye have made our savour to be abhorred in the eyes of Pharaoh, and in the eyes of his servants, to put a sword in their hand to slay us.
And Moses returned unto the Lord, and said, Lord, wherefore hast thou so evil entreated this people? why is it that thou has sent me?
For since I came to Pharaoh to speak in thy name, he hath done evil to this people; neither has thou delivered thy people at all.
Pharaoh was the one who refused God and made even a heavier burden be placed on the children of Israel. The officers of the children of Israel went before Pharaoh and not God to seek mercy. Pharaoh refused to be merciful. Now as they are leaving Pharaoh they run into Moses and Aaron---and they blame Moses and Aaron for their current circumstances. They believed that they were God's messengers delivering God's word to them. Yet they blamed the messengers rather than Pharaoh.
Moses did turn to God and asked God why He did this evil thing. Moses wanted to know why did you send me...what happened...things are only getting worse...
I believe that God can handle our honesty...when you don't understand, when you are confused, frustrated take it to the Lord.
Moses could have been defensive with the children of Israel or got all macho on Pharaoh...instead he took his concerns to God.
Whenever, wherever, however God sends you forth always look to Him, turn to Him, seek His counsel and direction. Whether things look great or dangerous seek God first.
