Mighty Moses

Acts 7:17-22 
17 “But when the time of the promise drew near which God had sworn to Abraham, the people grew and multiplied in Egypt 18 till another king arose who did not know Joseph. 19 This man dealt treacherously with our people, and oppressed our forefathers, making them expose their babies, so that they might not live. 20 At this time Moses was born, and was well pleasing to God; and he was brought up in his father's house for three months. 21 But when he was set out, Pharaoh's daughter took him away and brought him up as her own son. 22 And Moses was learned in all the wisdom of the Egyptians, and was mighty in words and deeds.

God's people increased as promised until the new pharaoh came into power and enslaved them.  He tried to kill the male babies (God later takes their firstborn sons), but Moses is spared by God and even raised as Pharaoh's son.  So one of God's learned all the wisdom of the king as a son of a slave.  God knew what He was doing in so raising a deliverer for His people in His time.  The time of the promise to bring the people out of bondage after 400 years of servitude was near. So He saves us from the bondage of sin when the time of His Son comes for each of us in His appointed time.
