The agent of predestination is God. In his sovereignty he predesignates. Human beings are the object of his predestination. In short, this refers to God's sovereign plan for human beings, decreed by Him in eternity. It also includes whatever comes to pass in time and space.
Martin Luther (10 November 1483 – 18 February 1546) was a German monk, priest, professor of theology and iconic figure of the Protestant Reformation. He strongly disputed the claim that freedom from God's punishment for sin could be purchased with money. He confronted indulgence salesman Johann Tetzel with his Ninety-Five Theses in 1517. His theology challenged the authority and office of the Pope by teaching that the Bible is the only source of divinely revealed knowledge from God.
