Teaching from Martin Luther?

The central teaching of Martin Luther was the belief that salvation would be granted on the basis of faith alone rather than by works. He struggled with the Roman Catholic church's demands that one could only earn favour with God through good works. Through his in-depth study of the Scriptures, he reached the realisation that salvation is a gift of God's grace, received by faith alone and by trust in Christ's death on the cross as the only means to that salvation.
