I came across this reading from the preface of Calvin’s Commentaries on the psalms and thought I would share.
Thus it came to pass, that I was withdrawn from the study of philosophy,and was put to the study of law. To this pursuit I endeavored faithfully toapply myself in obedience to the will of my father; but God, by the secret
guidance of his providence, at length gave a different direction to my course. And first, since I was too obstinately devoted to the superstitions of Popery to be easily extricated from so profound an abyss of mire, 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, I yet pursued them with less ardor
