Then one of the elders said to me, "Do not weep! See, the Lion of the Tribe of Judah, the Root of David, has triumphed. He is able to open the scroll and its seven seals."
Jesus is not only a Lamb but also a mighty Lion. That's the duality of His nature has God: gentle yet powerful, slain but alive, sacrifice and priest. In Revelation, we learn Jesus is the One who comes and is able to open the scroll of God the Father's Plan of future events. Only Jesus has the authority to reveal what is going to happen. The fact that He is called the Lion of Judah refers back to Israel's (Judah's father) blessing in Genesis 49:9 which alluded to the Messiah being from the Tribe of Judah. Jesus has human, earthly, tangible, traceable ancestors. Jesus is fully man, yet also fully God.
He is also called the Lion because they are fierce animals. Jesus has fierce love for us. He is powerful and mighty, yet He cares for and protects His own, like a lion would a pride. How does this make you appreciate His love for you?
Since Jesus has triumphed, that means if we believe in Him and put our whole trust in Him, then we have already won! Will you give everything over to Him and praise Him for His triumphant entrance into the Throne Room of God to open the Scroll (Revelation 5)?
In His Love,
