How do we know the Sabbath commandment is still applicable today?

While some argue that the Sabbath was solely a Jewish observance, the New Testament reveals its significance for all believers. In Acts, the early church met on the first day of the week, acknowledging the resurrection of Christ as the focal point for worship. Moreover, Jesus emphasized the moral aspects of the law, including the Sabbath, in His teachings, indicating that its principles continue to hold weight. The shift from the Jewish Sabbath to the Lord's Day reflects the fulfillment of the law in Christ, yet the command to set apart a day for rest and worship remains for His people.
