How do we know that Scripture must be fulfilled?

The concept that all Scripture must be fulfilled stems from the nature of God as truthful and faithful. Luke 23 illustrates this, as numerous actions and events during the crucifixion fulfill Old Testament prophecies about the Messiah's suffering and death. Paul reminds us in Romans 15:4 that the things written before were for our learning and hope. This assurance extends beyond Christ’s first coming—believers are to trust that God will also fulfill His promises regarding their salvation and the completion of His plan. Historical accounts and prophetic literature in Scripture collectively demonstrate that every utterance of God will come to pass, establishing a firm foundation for our faith.
