Question 2 continued: Whom should we worship?
The Lamb that was slain (5:6, 9) With his blood he purchased men for God from every tribe and language and people and nation. The Lamb of God redeemed them with his own blood. The lamb, the symbol of innocent sacrifice from the Old Testament, made payment for the sin debt owed by the great multitude. It would be accurate to say that we are all blood-bought, redeemed for God, purchased from out of our sinfulness and rebellion.
This "multitude that no one could count, from every nation, tribe, people and language" has been made to be a kingdom and priests to serve our God. In the Old Testament, only one tribe out of the twelve was given the responsibility and privilege of being priests serving in the presence of God. Yet, after being purchased by the Lamb, every person serves in the presence of the Lord. There is no longer any separation between God and His people.
In a beautiful picture of unity in diversity with all racial, tribal, and social barriers erased, this multitude will cry out in a loud voice:
"Salvation belongs to our God, who sits on the throne, and to the Lamb." (7:10)
And we live in anticipation of this great promise:
"For the Lamb at the center of the throne will be their shepherd; he will lead them to springs of living water. And God will wipe away every tear from their eyes." (7:17)
