‘And Simon answered and said, “You pray for me to the Lord, that none of the things which you have spoken come on me.” '
Simon then pleads with Peter to pray that none of these things come on him. He probably did not know the context of Peter's quotations but recognised that they spelt awful calamity. Nothing is further said about the incident. This leaving an incident in mid-air is typical of the Bible elsewhere. When Scripture leaves something in the air like this it usually signifies that what was spoken of followed. Thus we have the right here to assume that Peter did pray for him, and that he was forgiven. He was after all new in the faith and had needed his thinking sorting out, and deliverance from what had previously gripped him. And his request for their assistance in prayer was understandable in the light of Peter' strong language. He wanted Peter to remove the ‘curse' he had put on him. And we may assume that as Luke remains silent on the matter he intends us to see that that is what happened.
Looking back at the New Testament we forget that many new converts had no background in the things of God. While the ministry was to Jews or even to Samaritans they had the background of the Law to call on, but Gentiles and men like Simon had no background in the word of God. Their thinking was fashioned by the pagan world around them. Thus when they were converted their first faltering steps would often reveal them to be at fault. Simon was no exception. The point therefore here is that he learned a valuable lesson which would hopefully completely alter his way of thinking, and was also a salutary lesson for all who would read Luke's words.
