Christ: Ruler and Redeemer

Acts 7:35-37 
35 “This Moses, whom they rejected, saying, ‘Who made you a ruler and a judge?’—this man God sent as both ruler and redeemer by the hand of the angel who appeared to him in the bush. 36 This man led them out, performing wonders and signs in Egypt and at the Red Sea and in the wilderness for forty years. 37 This is the Moses who said to the Israelites, ‘God will raise up for you a prophet like me from your brothers.’

God was Israel's deliverer from Egypt; He just used Moses.  So they argued against God's deliverance, and were told a Prophet to come would later be raised up to listen to, the Messiah Jesus known as the Christ.  All the wonders God did in deliverance from bondage and in the desert were built on by Jesus continuing the work to prove He is that one.  He raised the dead, gave sight to the blind, wholeness to the lame, hearing to ears not hearing, and so much more.  So Stephen reminded them who Jesus is and of their continuing rebellion as a testimony against their rejection of God in Him.  Do not refuse Him.
