How do we know God's promises will come to pass?

God's promises are grounded in His unchanging character and sovereign will. As Isaiah 46:10 states, "Declaring the end from the beginning, and from ancient times the things that are not yet done," this illustrates God's capability to declare and bring about His purposes. The historical prophecies concerning Cyrus, as mentioned in Isaiah 44:28, further confirm that God not only knows the future but actively directs it, ensuring that His Word will be fulfilled. Therefore, believers can trust that what God has promised will be accomplished, despite any human opposition or delay.
