Johann was the son of Gottfried Winckler, town clerk of Lucka.
He became a theology student at the University of Leipzig, when August Francke and J. C. Schade were holding their Bible readings, and his sympathies thereafter were with the Pietist movement. In 1692, he was appointed preacher to St. George’s Hospital at Magdeburg, and afternoon preacher at St. Peter’s Church there. He became chaplain to the Prince Christian Ludwig Regiment in 1695, and went with it to Holland and Italy. After the Peace of Ryswijk in 1697, he toured Holland and England. Returning to Magdeburg, he was appointed in 1698 diaconus of the cathedral there, and in 1703 inspector of the Holzkreis. In 1714, he became chief preacher at the cathedral, and in 1716, Consistorialrath.
