Though there is some debate as to just what the scroll that is depicted here in Revelation represents, in context, it seems that the scroll represents God’s redemptive plan for history, namely as is unfolded in the Lamb’s Book of Life. For that book to be opened, God’s righteous judgments against mankind need to be brought about (the opening of the seals). And Jesus is the only one who is worthy to unfold the plan of God in history.
Paul speaks of God having chosen his elect since before the foundation of the earth (Ephesians 1:4). That means that before God even began the work of creation, God wrote this scroll. If you are a believer in Jesus Christ, he wrote your name on this scroll before the ages began. And he sealed the scroll up with the judgments that would come as a result of the fall. Yet, these judgments are only opened up through the mitigation of Christ—Christ who God promised to Adam and Eve at the fall (Genesis 3:15). Were it not for Christ, we would have perished long ago. Judgment and redemption are intimately interwoven with the person of Christ. What a gracious God we have. What a wonderful savior we have been given!
A wonderful savior is Jesus my Lord,
a wonderful savior to me;
He hideth my soul in the cleft of the rock.
where rivers of pleasure I see.
He hideth my soul in the cleft of the rock
that shadows a dry, thirsty land;
he hideth my life in the depths of his love,
and covers me there with his hand,
and covers me there with his hand.
