Scott Allen leads today's lesson from one of the most significant of all the psalms, Psalm 110. In this psalm of David, a future ruler is foreseen. This ruler from David's line is so special that even David himself calls Him Lord. But how could the Son of David precede his own ancestor? We soon learn that the Messiah was not a mere man or even an angel but the eternal Son of God, and not merely a kingly ruler but also a timeless priest. In comparing the Messiah to a mysterious figure named Melchizedek, we learn the true nature of the Messiah's redemptive mission. Every person finds himself or herself either aligned with or judged by Messiah, who promises to return to our world again with grace for believers and punishment for the unrepentant.
