In Samaria, there is an influential and respected man named Simon who uses magic powers. However, his motivation is not to serve the people, but to gain power and honour. Simon is enthusiastic about the power that emanates from Philip. That is why he is baptised with others (Acts 8).
Simon does not seem to have received the Holy Spirit. It is possible to believe with the head without the heart being touched by the Holy Spirit. A renewal of the heart is needed.
By Simon, it is clear that his thinking has not been renewed. He remains in his magical thinking. He wants to use God. He is jealous and wants to buy spiritual gifts with money. But Jesus teaches: ‘Freely you have received, freely give’ (Matthew 10:8). Simon is not interested in serving, but in earning.
When Peter uncovers his misbehaviour, Simon only wants to be spared the consequences of his transgression. Although he is baptised, he does not repent. Justin, the martyr (100-165 from Samaria), later reports that Simon separated from the church and founded his own movement.
Faith is more than intellectual acceptance. Faith means receiving the Father and the Son through the Holy Spirit and being changed by him.
