Sincere Repentance?

Acts 8:22-25 
22 Repent therefore of this your wickedness, and pray God if perhaps the thought of your heart may be forgiven you. 23 For I see that you are poisoned by bitterness and bound by iniquity.” 24 Then Simon answered and said, “Pray to the Lord for me, that none of the things which you have spoken may come upon me.” 25 So when they had testified and preached the word of the Lord, they returned to Jerusalem, preaching the gospel in many villages of the Samaritans.

After Simon wanted to buy God's power and the ability to give it to others, he prayed only that nothing bad would happen to him.  He was told his sin and bitterness bound him until that evil was turned away from, but we do not know how sincere or complete Simon's answer was. The apostles then continued to  proclaim God's good words of life to many in Samaria. Whether or not sincerity is returned when the gospel is told, it must go on to reach the hearts of those with ears to hear.
