Why is the concept of the Lion and the Lamb significant in Christian teaching?

In Revelation 5, Jesus is revealed as both the Lion of the tribe of Judah and the Lamb that was slain, an essential concept in Reformed theology. The Lion symbolizes Christ’s power, majesty, and authority as the conqueror over sin and death. In contrast, the Lamb represents His sacrificial role in taking away the sins of His people (John 1:29). This dual imagery emphasizes that Christ dominates sin and evil while simultaneously offering Himself as a pure sacrifice, thus fulfilling the requirements of the law and providing redemption for humanity. Believers are called to acknowledge both aspects as integral to understanding Jesus' mission and His reign.
