Regarding the above, how do know that Jesus wasn't speaking prior to His resurrection?
The phrase "The Son of Man coming in His kingdom" is erroneously interpreted to refer to Jesus' return to the earth to end the age. However, Jesus was speaking about Peter, John and James seeing Him in His glorified state. Below is the entire context:
"27But I tell you truthfully, some who are standing here will not taste death until they see the kingdom of God.”
28About eight days after Jesus had said these things, He took with Him Peter, John, and James, and went up on a mountain to pray.
29And as He was praying, the appearance of His face changed, and His clothes became radiantly white.
In verse
27, when Jesus says "some who are standing here will not taste of death," He is referring to Peter, John and James, which He took up the mountain with Him. Then in verse 28 is says "About eight days after Jesus had said these things" which means that what is about to be said is linked to Verse 27. In other words, eight days after the Lord had said "there be some standing here who will not taste of death until they see the Son of Man coming in His glory," was referring to Peter, John and James seeing the Lord in His glorified state and has nothing to do with the Lord's return to the earth to end the age. The preterist love to twist this so that they can attempt to use this as proof that the Lord had already returned in 70 AD.
Some who are standing here = Peter, John and James
The Son of Man coming in His kingdom = Fulfilled when Peter, John and James saw Jesus transfigured into His glorified state.
Jesus used the same phrase in another scripture:
"But if I drive out demons by the Spirit of God,
then the kingdom of God has come upon you."
In the verse above, did Jesus mean that the end of the age had come by saying that "the kingdom of God has come upon you?" No! The kingdom of God coming upon them was in reference to the Lord casting out demons by the Spirit of God. In the same way the reference to "those standing here will not taste of death
till they see the kingdom of God" is referring to Peter, John and James seeing the Lord's transfiguration into His glorified state.
The above is another scripture that the preterist love to twist in order to support their belief that Jesus has already returned. And that by interpreting "this generation" as referring to the one that Jesus was living in, which is false! Below is the entire context:
"Now learn this lesson from the fig tree: As soon as its branches become tender and sprout leaves, you know that summer is near.
33So also, when you see all these things, you will know that He is near, right at the door.
34Truly I tell you, this generation will not pass away until all these things have happened."
In the scripture above a comparison is being made:
Trees blossoming = Summer is near
All of these signs taking place = The Lord is near to end the age
The generation that the Lord was speaking of, is directly linked with all of those signs that He listed. Therefore, the generation that Jesus is referring to, is the one where those signs take place. Without them, we have no fulfillment. And because Jesus is speaking about the events which must take place leading up to His return to the earth to end the age, then the seals, trumpets and bowl judgments which are listed in Revelation must also take place. And believe me, the world has not seen those events by any means. By the time the seventh bowl has been poured out, the majority of the earths population will have been decimated and all human government dismantled.
In Matt.24:31 when Jesus returns to the earth, scripture states that "every eye will see Him and all the tribes of the earth will mourn because of Him." When did this happen? We have no record of this!
At that same time, Jesus sends out His angels to first gather the weeds and then the wheat, which are those who will have made it through the entire tribulation alive. When did this happen? That would be, never!
Revelation 19:11-21 is a detailed account of Jesus return to the earth to end the age. At that time the beast and false prophet will be captured and thrown alive into the lake of fire. When did that happen? We would have had to also see the abomination set up and the emergence of the mark of the beast. None of those events have taken place.
Another event that takes place as Jesus is returning to the earth, is that an angel will be calling all of the birds of the air to come and gather themselves to the great supper of God, to eat the flesh of kings, general, mighty men and all people great and small, free and slave. When did that happen?
I haven't even hit on the events of the seals, trumpets and bowl judgments which must take place leading up the Lord's return. To believe that the Lord has already returned to the earth is utterly ridiculous to even entertain.
