Through intensive Bible study, Adventists came to understand the significance of the law in the Most Holy Place of the heavenly sanctuary. Looking into the heart of God’s law, they also discovered the significance of the Sabbath, the fourth commandment. In fact, this commandment more than any other clearly identifies God as our Creator, the foundation of all true worship—a theme that will be especially relevant in the final days of earth’s history (see Rev. 14:6–12).
