启示录 5 章有七印的书卷。 谁可以打开它？

The scroll was of papyrus or leather. Pieces of fragile papyrus about 10 inches wide were pasted together to make a long roll. The Old Testament was written on these rolls. It was a painful labor to copy without errors the rolls, therefore a very costly and precious piece. One sroll contained a part of the Old Testament book. The complete Old Testament was kept in the synagogue. And on the Sabbath, a roll was requested to read from (Luke 4:16-20). Normally only on the inside was written. Here in Revelation the roll was written on the inside as well as the outside and sealed with seven seals. A scroll written on the inside and outside was called an opishograph, representing the fullness of the divine foreknowledge and counsels. History will not end until God's purposes has fully consummated.
In the Roman world seven seals were normally used at a testament. A testament was witnessed by seven witnesses who applied each his own seal to the testament.
The clue to this roll is Ezekiel 2:1-10. There Ezekiel needs to prophesy against the impudent and stubborn house of Israel, which we can compare with the impudent and stubborn people today. The scroll he saw was written on the front and on the back, and there were written on it words of lamentation and mourning and woe. Like this scroll. This scroll contains the prophecy of the end events including salvation of people as well as God's judgment about the wicked.
No one in Heaven nor on earth is able to open nor to look into it. However, verse 5 gives the solution. Jesus Christ Who died (testament) for the sin of men, and has risen from the dead, ONLY HE is allowed to open this scroll. He has paid the price!
The lion from the tribe Judah, the root Davids, is without question the Lord Jesus Christ who is born from the tribe Juda, from king David ( see the genealogy of Jesus Christ in Matthew 1:1-17). The Lord Jesus Christ is the only one, Who is qualified to open the scroll.
The Lord Jesus is also presented as the slaughtered Lamb at the Cross of Golgotha (1 Corinthians 5:7 "For Christ, our paschal lamb, has been sacrificed").
He has conquered, literally HE HAS WON THE VICTORY. Which victory? Hebrews 2:14-15 and Col. 1:15.
On the cross and resurrection He destroy death and thereby disarmed satan and principalities and powers (that is the evil powers).
The significance of the lamb, we know from the Pascha. Isaiah 53:7-8.
The seven horns represents the fullness of power and strength (Deut. 33:17; Ps. 18:2, 112:9). The seven eyes represent the fullness of vision. Nothing is hidden from God, God sees into the heart and mind of men. He knows man's deepest motives and thoughts. His vision is at every place on earth, nobody can hide.
The Greek word translated by SLAIN is only used in Rev. 5:6, 9, 12 and 13:8 for the death of Jesus, but an echo of Isa. 55:7 He was "led to the slaughter".
Their number was myriads of myriads (total: 100,000,000) and thousands of thousands (total: 1,000,000) a number mentioned before in the Bible, in Daniel 7:9-10. The number 101,0000,000 gives a reasonable impression of the number of angels who are present to praise the Lord Jesus Christ.
Every creature in heaven and on earth and under the earth and in the sea. The creatures in Heaven are clearly the angels and the believers in Heaven. But what about on earth and under the earth and in the sea. Given the time, it is soon after the Rapture of the Church, so not yet saints killed in the Great Tribulation. I think we need to look at Genesis 4:10 The voice of your brother's blood is crying to me from the ground. Which I think means that animals, plants and trees are crying to God that Kain killed his brother Abel. Jesus cursed the fig tree. We have no knowledge about animals, plants and tree, but they are Gods creation (may we say creatures?).
It also gives an idea of the multitude of angels who are present around the earth to protect the Christian believers against evil, Satan and the power of darkness (his evil angels).Therefore, do not let us, Christian believers, forget what a power the Lord God has. A Heaven that can accommodate so many persons, that is God's creation for God is Almighty. God is the One Who will conquer Satan and his evil angels, and He is the One Who already reigns through the Holy Spirit, Who dwells in every Christian believer, throughout the earth. Therefore allow the Holy Spirit, to do His work in you, because the works of the Holy Spirit must be seen as God already reigns on earth resisting the evil (Satan and his followers). In order that progressively more people will learn that Jesus Christ is their personal Savior and he saved them for eternity. Then they will become part of the multitude, who will worship the Lamb, the Lord Jesus Christ. And if you have not yet accepted Jesus Christ as your personal Savior, DO NOT POSTPONE! Later it is too late, and then the Lord Jesus Christ will have taken up the church (the reborn) into the heaven.
