A dramatic scene, beyond our human comprehension, but powerful, is depicted in Revelation 4 and 5. I invite you to read it here. (Better yet, click the speaker icon and listen to Max McLean read it.)

In the Spirit, the apostle John was transported to the throne room of God, where day and night praise and worship rose from the four living creatures and the 24 elders who surrounded God’s throne. Among their songs was this one, “Holy, holy, holy is the Lord God Almighty, who was, and is, and is to come” (4:8).

But when John saw in the right hand of God a scroll with writing on both sides and sealed with seven seals, and learned that there was no one in heaven, on earth, or under the earth who was worthy to open the scroll, he wept and wept (5:1-4).

Do not weep, said one of the elders. “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” (v 5) 

None but Jesus is worthy.

 In his death he bore the sins of the world in his own body—he took them upon himself because we cannot save ourselves. Not by our own righteousness. Not by our good works. We cannot buy our way out of our sins. But Jesus paid the price for us!

And in his resurrection he conquered death. At her brother’s grave he told Martha, “I am the resurrection and the life. The one who believes in me will live, even though they die; and whoever lives by believing in me will never die” (John 11:25-26). He was talking about eternal life.

By the blood he shed on the cross he purchased for God persons from every tribe and language and people and nation (5:9). The good news of Jesus is for all people.
So we join our voices with the vast throng in Revelation singing:

“Worthy is the Lamb, who was slain,
to receive power and wealth and wisdom and strength
and honor and glory and praise!” (5:12)

I was curious about the scroll with seven seals and found a couple of links that you might enjoy.
