Protestant reformer John Calvin was born on this day in history: July 10, 1509. Calvin was a prolific writer and theologian. His beliefs about God's sovereignty and predestination are at the core of the belief system called Calvinism.
In the book Commentary on the Book of Psalms Calvin describes his conversion experience:
"God by a sudden conversion subdued and brought my mind to a teachable frame, which was more hardened in such matters than might have been expected from one at my early period of life. Having thus received some taste and knowledge of true godliness, I was immediately inflamed with so intense a desire to make progress therein, that although I did not altogether leave off other studies, yet I pursued them with less ardour."
