Serving Christ and His church as a pastor, theologian, and military chaplain, John Owen lived through one of the most tumultuous periods in England's history. His own life was marked by turbulent changes as his position rose and fell according to the tides of English politics. One day he was preaching before Parliament, the next he was fortunate just to escape with his life. But through it all, Owen remained steadfast in his faith in the triune God of the Bible. In The Trinitarian Devotion of John Owen, Dr. Sinclair Ferguson explores the life and thought of this remarkable preacher and theologian, with a focus on Owen's Trinitarian theology. Far from being a minute point of doctrine, God's triune majesty was central to Owen's Christian life and devotion. This book presents Owen's theology of the Trinity as a door through which Christians today can find incredible blessing. This book is part of the Long Line of Godly Men Profile series, edited by Dr. Steven Lawson.
