How do we know that God's decrees are irreversible?

The doctrine of God's sovereignty is foundational in Reformed theology, asserting that all of His decrees are foreordained and unchangeable. Balaam's interactions in Numbers 22 and 23 illustrate this truth; God declared that the people He has blessed cannot be cursed and that His word remains unaltered. The irreversible nature of God's plans showcases His power and authority over creation, emphasizing that His will comes to pass without fail (Isaiah 46:10). This assurance grants believers confidence in His promises.
