There are two ways to approach Christianity: return to the Bible or revise it until it agrees with us. Sola Scriptura means Scripture alone is the final authority, measuring every teacher, tradition, creed, and religious claim by God’s Word. This lesson calls believers back before Catholicism, before Protestant denominationalism, and back to Christ, the apostles, and the original gospel. The Bible gives the truth that saves, the pattern that guides, and the word that will judge us on the last day. Faithful disciples do not update Scripture; they open it, obey it, and let it change their hearts.
