The Mystery of Melchizedek

This Sunday we continue our summer series in the Psalms. We will take one last look at the mysterious mention of the character Melchizedek in Psalm 110:4. Before Psalm 110, Melchizedek has only appeared once in the scriptures, and even that appearance was mysterious (Genesis 14). Melchizedek was the king of Salem, and priest to the most high God (Gen 14:18). For someone so mysterious, why is he so important? How will understanding the mystery of Melchizedek help our faith sing along with Psalm 110?
