What does the Bible say about God's unexpected actions?

In Isaiah 64:3, the prophet reflects on how the Lord has acted in history, particularly noting that God has done 'terrible things which we look not for.' This is a recurring theme throughout Scripture, where God intervenes in unexpected ways to accomplish His purposes. For instance, the Israelites could not have anticipated the miraculous events during the Exodus, such as the parting of the Red Sea, which demonstrated God's sovereignty and power over nature. Similarly, believers today may not foresee the ways the Lord will answer their prayers or bring about change, reminding us to trust in His divine wisdom and timing.
