History records Martin Luther as a savior of Christianity. He was concerned with the well-being of the Catholic Church and its policy of granting forgiveness through indulgence rather than penance. Luther's actions were neither cinematic nor groundbreaking. The message of 95 Thesis gave the summary and expressed the feelings of many of his peers already had about the corruption of Christ's teachings.
Luther illustrated the spiritual, material, and psychological truths behind abuses in the practice of buying and selling indulgences. He was not out to pick a fight or to have his own way; his purpose was to uphold the truth, for the cause of Christ.
Luther came to understand justification as entirely the work of God. This teaching by Luther was clearly expressed in his 1525 publication On the Bondage of the Will , which was written in response to On Free Will by Desiderius Erasmus (1524). Luther based his position on predestination on St. Paul's epistle to the Ephesians 2:8–10 . Against the teaching of his day that the righteous acts of believers are performed in cooperation with God, Luther wrote that Christians receive such righteousness entirely from outside themselves; that righteousness not only comes from Christ but actually is the righteousness of Christ, imputed to Christians (rather than infused into them) through faith.
