What do the words “God have mercy” mean if not the strong belief that God can forgive all sins and every repenting sinner? These words actually mean “God, have mercy of me, the sinner, the miserable!”

This short prayer only has three words but is so strong that destroys all evil plans as soon as we say it. God left to us the prayer as one of the easiest way of salvation. In His holy glory, the Creator wants people to come to him.
