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.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
