In this thorough defense of Sabbatarianism, Jon English Lee captures insights from the entire theological encyclopedia—from exegetical and biblical theology to systematic and historical theology. Lee anticipates and responds to thorny questions like these: Does the fourth commandment bind believers today? Why do we now celebrate the Sabbath on the first day of the week? And what did Paul mean in Colossians 2:16–17? May the Lord use this helpful treatise to renew your delight in the Sabbath as well as your enjoyment of the God who graciously gave it to us (Isa. 58:13–14).
