As the French soldier dug in the desert sand, reinforcing the defenses of his army’s encampment, he had no idea he would make a momentous discovery. Moving another shovel-full of sand he saw a stone. Not just any stone. The Rosetta Stone, containing laws and governance from King Ptolemy V written in three languages. That stone (now housed in the British Museum) would be one of the most important archaeological finds of the nineteenth century, helping to unlock the mysteries of the ancient Egyptian writing known as hieroglyphics. For many of us, much of Scripture is also wrapped in deep mystery. Still, the night before the cross, Jesus promised His followers that He would send the Holy Spirit. He told them, “But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come” (John 16:13). The Holy Spirit is, in a sense, our divine Rosetta Stone, shedding light on the truth—including truths behind the mysteries of the Bible. While we are not promised absolute understanding of everything given to us in the Scriptures, we can have confidence that, by the Spirit, we can comprehend everything necessary for us to follow Jesus. He will guide us into those vital truths.
