God's will is unchangeable because His sovereign purpose is always fulfilled, as stated in Isaiah 14:24.
The unchangeability of God's will is foundational to the assurance we have as believers. When God declares His intentions, it is always accomplished without fail. Isaiah 14:24 indicates that the Lord of Hosts has sworn that His purpose will stand. God, being omnipotent and free from the limitations of time and space, cannot be thwarted by human decisions or any other force. This sovereignty gives us confidence that what God promises will come to fruition, and we can trust in His plans for our lives and the world, knowing that nothing can prevent His ultimate purpose.
