The Lion has Conquered
Revelation 5:5 (ESV) … “And one of the elders said to me, “Weep no more; behold, the Lion of the tribe of Judah, the Root of David, has conquered, so that he can open the scroll and its seven seals.”
Jesus is both the Lion and the Lamb. The Lion of the tribe of Judah represents the kingship of the Lord Jesus Christ. The lamb slain from the foundation of the world represents the priestly office of the Lord Jesus Christ, who became the sacrifice for our sins to bring peace. As the Lamb of God that takes away our sins, we adore and worship him. As the Lion of the tribe of Judah, we worship Him in fear and trembling.
As believers, we will one day face the judgment seat of Christ, where we will give account of our lives as Christians in the service of our King. This will be a day of fear and trembling. Even now, we are being judged and chastened by our Lord.
In his book The Final Quest Rick Joyner is told by Wisdom that Jesus is the Lamb slain for our sins to the young believers. But to the maturing Christians, Jesus becomes the Lion who is judging our sins, so that we may live a holy life here on earth. To the fully mature believer, Jesus is both the Lion and the Lamb, as we have learned to worship Him in fear as our Lord and in adoration as our Savior.
