Buying a blessing. ( Acts 8 v 20 )

In Acts 8  v 9 ff, we read of a man called Simon the sorcerer who had great influence with the people of  Samaria with his magic arts. The people were so impressed with him they believed he exercised divine power.but things changed,when  the gospel was preached by Philip, The result was, many believed in Christ and were baptised, Simon professed also faith  in Jesus, he was astonished at the great signs and miracles performed by Philip.In the meanwhile, Peter and John appeared on the scene.Many were receiving  the Holy Spirit and this impressed Simon, so much so , that he went to the apostles and offered them money to receive the Holy Spirits power.Peter said to him ,''May your    money perish with you, because you thought you could buy the gift of God with money ''( v 20 ) One of the things that  kicked off the reformation was  the practice by the Roman Catholic church selling indulgences as payment for peoples  sins being forgiven,also there was also a charge when a mass was carried out,no money no mass. Well what about the prosperity preachers,by your giving you will receive a blessing,now they way they teach it appears that one is buying a blessing of God. All these people are followers of Simon the sorcerer, and they need to repent of this wickedness.
