Revelation 5:1-14 Then I saw in the right hand of him who was seated on the throne a scroll written within and on the back, sealed with seven seals. 2 And I saw a strong angel proclaiming with a loud voice, "Who is worthy to open the scroll and break its seals?" 3 And no one in heaven or on earth or under the earth was able to open the scroll or to look into it, 4 and I began to weep loudly because no one was found worthy to open the scroll or to look into it. 5 And one of the elders said to me, "Weep no more; behold, the Lion of the tribe of Judah, the Root of David, has conquered, so that he can open the scroll and its seven seals." 6 And between the throne and the four living creatures and among the elders I saw a Lamb standing, as though it had been slain, with seven horns and with seven eyes, which are the seven spirits of God sent out into all the earth. 7 And he went and took the scroll from the right hand of him who was seated on the throne. 8 And when he had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb, each holding a harp, and golden bowls full of incense, which are the prayers of the saints. 9 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." 11 Then I looked, and I heard around the throne and the living creatures and the elders the voice of many angels, numbering myriads of myriads and thousands of thousands, 12 saying with a loud voice, "Worthy is the Lamb who was slain, to receive power and wealth and wisdom and might and honor and glory and blessing!" 13 And I heard every creature in heaven and on earth and under the earth and in the sea, and all that is in them, saying, "To him who sits on the throne and to the Lamb be blessing and honor and glory and might forever and ever!" 14 And the four living creatures said, "Amen!" and the elders fell down and worshiped.
One thing we can clearly learn from this passage is that the Lion of the tribe of Judah is the Lamb of God who took away the sins of the world and made the gift of forgiveness of sin available to all who repent and believe the gospel. Jesus is the Lamb of God, is God (see Titus 2:11-14).
Jesus is the only one who can reveal what is to happen after 90 AD when the Revelation was written by John. The seven seals reveal to us what will happen from 90 AD to the time of the 2nd coming of Jesus to judge and rule the world.
Jesus will answer all the prayers of the people of God crying out for deliverance from sinful people. He will answer the prayers of the people being persecuted and killed today by ISIS. The slain Lamb is also the conquering King and is worthy to receive power and wealth and wisdom and might and honor and glory and blessing forever and ever.
We are being given a picture in the first seven seals of what has occurred from the 1st century and what is yet to come beyond our present time. From our 21st century position, we can see clearly the reality of the seven seals and likely live close to their fulfillment with the coming of Christ. We need to be diligent to carry out our God-given assignments and bring as many as we can with us into the new heavens and earth.
