The day they chose the Passover lambs, Jesus rode into Jerusalem. A children’s choir prophesied the ancient Hosanna, and the Lamb was revealed to be the King! The people had their moment of opportunity to chose the Lamb of God.
When we properly behold the Lamb of God, we see that He is King, and we must choose the Lamb of God to be the King of Kings. The Lamb is the King. The Lamb is the Lord. It is not possible to have a Savior who isn’t Lord!
