Juan Oosthuizen is an independent Bible student and Christian writer devoted to the careful study of Scripture and the defense of biblical truth. His work focuses especially on the Sabbath as revealed in creation, affirmed in the moral law, embodied in the life of Christ, and upheld throughout redemptive history. With a deep respect for the authority of Scripture, he approaches theology not as speculation, but as submission to the Word of God. Through rigorous biblical analysis and reverent engagement with both Old and New Testament texts, Oosthuizen seeks to demonstrate that the Sabbath is not a ceremonial shadow abolished in Christ, but a living sign of God’s creative and redemptive power. His writing reflects a conviction that faith and obedience are not opposed, but united in Christ, and that true Christian discipleship includes loyalty to God’s commandments. Case for the Sabbath in Christ is written for thoughtful readers who desire a Scripture-centered understanding of the Sabbath, free from tradition-driven assumptions and grounded in the testimony of the Bible itself. Oosthuizen writes with the conviction that truth must be tested by Scripture alone, and that the Sabbath remains a vital gift from God to humanity—resting at the heart of the gospel, the character of Christ, and the final call to worship the Creator.
