Updated to Modern English "A Treatise on God's Free Grace and Man's Free Will" by William Perkins offers a profound exploration of theological concepts from a Reformed perspective. Perkins critiques the Roman Catholic Church's views on grace and free will, arguing that they undermine the sovereignty of God's grace. He highlights two key concerns: the overemphasis on human free will and the idea of human cooperation with God's grace. Perkins firmly asserts the importance of relying on God's grace alone for salvation and godliness. This book is a compelling call to recognize our dependence on God's grace for all spiritual good and serves as a vital resource for those seeking a deeper understanding of divine grace and human agency.
