There eis a great deal that I love about this song. I think most of all it expresses well the consequence of what Jesus did on the cross.
Jesus died for a purpose, and part of that Purpose was to enable believers to enter into the presence of God without being obliterated because of our sin. Jesus took all of our sin upon Himself and paid sin’s price—death—that we might be made holy.
I also love the all-encmpassing breadth of the song. Undoubtedly the latter section of the song — a bridge, I suppose— is based on Revelation 5:9-10:
And they sang a new song, saying,
“Worthy are you to take the scroll
and to open its seals,
for you were slain, and by your blood you ransomed people for God
from every tribe and language and people and nation,
10 and you have made them a kingdom and priests to our God,
and they shall reign on the earth.”
When I hear this song, I think forward to the day when finally, finally we behold Jesus in all His glory; when the Bride marries the Lamb, when we stand before the throne of God, and worship Him in truth for who He is, as we behold Him face to face.
