It is taught in the Bible that the ancient prophet Enoch did not experience death but was taken by God. So from the beginning of the Judeo/Christian history, it has been believed that God could make it so there are some in this life who do not taste of death up until they are either changed in the twinkling of an eye or eventually do experience death at a much later time. Because Jesus was the very first to resurrect, all who experienced death from the time of Adam until the time of Jesus had to wait until after Jesus' resurrection before they could come forth from the dead and reunite their spirits with their bodies. In the case of Enoch, he did not see death but was translated by God. To be translated is a process of living beyond a normal life span for an extended amount of time until one is either changed in the twinkling of an eye from the translated state into a resurrected state or until the translated being dies at a much later date and then is resurrection just as other dead people are who die naturally.
Hebrews 11:5
5 By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God.
Jesus, during his minister on earth told a group of his disciples that that there were some among them that would not taste of death until they saw the son of man coming in the power of the kingdom of God.
Matthew 16:28
28 Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
Luke 9:27
27 But I tell you of a truth, there be some standing here, which shall not taste of death, till they see the kingdom of God.
Mark 9:1
1 And he said unto them, Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.
One of those disciples of Jesus who received the promise of Jesus that he would be translated and not taste of death was the Apostle John. This is spoken of by Jesus in the final chapter of John.
John 21:21-25
21 Peter seeing him saith to Jesus, Lord, and what shall this man do? (speaking of John)
22 Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me.
23 Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee?
24 This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true.
25 And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen.
At a bear minimum, the translation of John will go on until the Lord comes again upon the earth. At that time, it may be that John will then suffer death but it will not happen until the second coming of Jesus Christ. Notice that Jesus did not say that John would not die, but that he said, "If I will that he tarry till I come, what is that to thee?" the promise to John was that he would tarry until the second coming. At that time, he may suffer death. Some believe that John and perhaps Elijah will be the two witnesses that are prophesied in Revelation 11 who will die and rise after three and a half days. Elijah did not taste of death while of this earth but was taken up in a whirlwind.
The men in the video spoken of in my first post make the assumption that everyone in the generation that existed at the time Christ was on the earth all lived a normal lifetime and died at an average age of dying. But God has the power to extend life and has done so for certain people who have been on this earth. To assume that the entire generation of those who lived at that time have passed away is to not have faith in the words and power of Jesus Christ. There are those who claim that John died but there is no definitive proof that he died.
Enoch is not ancient .. It dates to about 300 BC.
John of Patmos was talking to the people of the first century not thousands of years into the future. Scofield encourages some Christians to assign future involvement of the United States or Russia or the Arab world to Revelation. It was written for the Jews not the world. Be wary of charlatans.
