The 21 judgements of the tribulation: The fifth seal

And when he broke the fifth seal, I saw underneath the altar the souls of those who had been slain because of the word of God, and because of the testimony which they had maintained; and they cried out with a loud voice, saying, "How long, O Lord, holy and true, wilt Thou refrain from judging and avenging our blood on those who dwell on the earth?" And there was given to each of them a white robe; and they were told that they should rest for a little while longer, until the number of their fellow servants and their brethren who were to be killed even as they had been, should be completed also.
Inasmuch as these individuals paid the ultimate sacrifice for God they are kept at the place nearest to God, the very place from which God receives fragrant aromas, the altar of incense. We should discern that God finds great pleasure in these souls.
The souls; this term is used twice in the Revelation . In both cases, those represented have not been resurrected.
Who had been slain; Only those recently killed are in focus. This point is defended by the martyrs’ own statement that God is to avenge their blood "on those who dwell on the earth."
How long; the importance of the martyrs comes to light at this point. They question the Lord concerning their persecutors. The phrase "how long?" in the context of a prayer is not uncommon in Scripture—particularly the Old Testament. The martyrs cry out for vengeance.
" Wilt Thou refrain from judging and avenging" is the essence of their question. It is critical that the reader understands that at this point in the narration, God has not begun to judge and avenge.
"Our blood"; this is the reason God is implored to take vengeance. These individuals died violent deaths, which demands justice.
"Those who dwell on the earth"; These are the lost who are responsible for the death of the souls under the alter.
A white robe; white garments are clearly the proper attire of those in the presence of God.
Rest, is the second of two commands the martyrs receive from God. This indicates that the souls were in a state that allows for refreshment from the labors of this life.
Fellow servants and their brethren; In every case, faithful followers of God are intended. These are clearly tribulation saints.
Who were to be killed, is a clear indication that God has a set number of those who will be killed during the tribulation. These are killed for their faithfulness. How many people will actually be killed may be indicated by the phrase "a little while longer." This tells us how long the killing will last. The exact Greek grammatical phrase occurs in John 7:33 and 12:35. The time represented by the phrase in John’s gospel could be from several days to a little more than a year, but the time represented in the Revelation by "a little while longer" is certainly not indefinite. Therefore, the number of those to be killed is not unlimited. Of particular interest is the fact that Revelation 10:6 announces that "there shall be delay no longer." Again, it is quite clear,the odds of your surviving the seven year tribulation are slim to none.Why risk death when Jesus offers you salvation and eternal life and a way by which you never have to die, the rapture.
You can ask the Lord to be your Savior right now by praying the words below:
“Father, I know that I have broken your laws and my sins have separated me from you. I am truly sorry, and now I want to turn away from my past sinful life toward you. Please forgive me, and help me avoid sinning again. I believe that your son, Jesus Christ died for my sins, was resurrected from the dead, is alive, and hears my prayer. I invite Jesus to become the Lord of my life, to rule and reign in my heart from this day forward. Please send your Holy Spirit to help me obey You, and to do Your will for the rest of my life. In Jesus' name I pray, Amen

Thanks for the information/interpretation. But I have to disagree with placing a prayer at the bottom in an attempt to save people. Although it may result in their salvation, there is a greater chance that it will mislead them.
