What does the phrase 'the Lamb slain from the foundation of the world' mean?

The phrase 'the Lamb slain from the foundation of the world' signifies that God's plan for salvation through Christ was established before creation itself. This profound truth suggests that the necessity of Christ's sacrificial death was known to God from the very beginning, indicating His sovereignty in redemptive history. Revelation 13:8 highlights this eternal purpose, emphasizing that the provision for redemption existed even before the fall of humanity. This perspective should inspire awe and reverence among believers, as their salvation is rooted in God’s eternal and sovereign decree, and reflects His glory and grace throughout all ages.
