What does the Bible say about the necessity of Christ's coming?

The necessity of Christ's coming is woven throughout the scriptures, particularly through the prophecies of Moses and the prophets. In Acts 26:23, it declares that Christ should suffer and rise from the dead, demonstrating that His coming was not accidental but ordained by God. This necessity highlights the eternal covenant initiated before the foundation of the world, where God decided to redeem His people through Christ's sacrifice. The entire creation and the unfolding of redemptive history were designed to showcase His glory through Christ's redemptive work, laying the groundwork for salvation that is complete and sovereign, not reliant on human actions.
