When Moses does battle with the greatest face of personified evil on earth in pharaoh of Egypt, things (apparently) backfire and take a turn for the worse. Moses expressed his disappointment to God and asks ‘Why did You send me? You have NOT delivered!’ But God assures Moses that indeed He will do business with pharaoh. It is a powerful parallel to the saving work of Jesus Christ, who went to the cross to die for sin. Here is my sermon on this from Exodus 5:1-6:1 (c.f. Matthew 1:1-11).
