How do we know that keeping the Sabbath is not for salvation?

The Sabbath serves as a sign and points to the need for spiritual rest found in Christ, not as a means to earn favor with God (Ezekiel 20:12). The Bible teaches that no one can fulfill God's law perfectly; thus, salvation cannot be contingent on our ability to keep the Sabbath or any other commandment. The Apostle Paul emphasizes that only through faith in Jesus can we find rest, for He has fulfilled the law on our behalf (Romans 10:4). Therefore, while resting and worshiping on the Sabbath may be beneficial, it is our faith in Christ that secures our salvation.
