What did the priest johann do that promoted martin luther to take action

Johann Tetzel sold indulgences promising people that bought them their entrance to heaven.

Explanation:

Johann Tetzel is remembered for selling indulgences on behalf of the Catholic Church, assuring buyers their entrance to heaven. This action was one of the reasons Martin Luther wrote the 95 Thesis, a list of questions proposed for debate.

Marin Luther was committed to the idea that heaven and salvation could only be achieved by repentance, faith and divine grace, things that money can't buy. He stated that selling indulgences made people avoid true repentance, and encouraged them to sin, with the idea that forgiveness could be bought.
