What does the Bible say about God's eternal law?

God's eternal law reflects His holy character and cannot be altered. As mentioned in Matthew 5:18, Jesus declares that not the smallest letter of the law will pass away until all is fulfilled, emphasizing the law's permanence in God’s plan. In Esther 8, we see a parallel with King Ahasuerus, whose decrees, though flawed, illustrate that once a decree is made and sealed, it cannot be revoked. This highlights the gravity of God's law, which declares that all who transgress it are justly condemned. The law reveals our sinfulness and our need for a Savior, as we are powerless to keep the commands perfectly.
