Matthew 16:28 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.
Matthew 17:1-11 (the very next passage) is the transfiguration of Jesus in all His glory
Matthew 23:36 Verily I say unto you, All these things shall come upon this generation.
"You snakes! You brood of vipers! How will you escape being condemned to hell? Therefore I am sending you prophets and wise men and teachers. Some of them you will kill and crucify; others you will flog in your synagogues and pursue from town to town. And so upon you will come all the righteous blood that has been shed on earth, from the blood of righteous Abel to the blood of Zechariah son of Berekiah, whom you murdered between the temple and the altar. I tell you the truth, all this will come upon this generation
"O Jerusalem, Jerusalem, you who kill the prophets and stone those sent to you, how often I have longed to gather your children together, as a hen gathers her chicks under her wings, but you were not willing.
As you can clearly see, Jesus was not referring to His second coming in this passage.
Matthew 24:34 Verily I say unto you, This generation shall not pass, till all these things be fulfilled.
"So when you see standing in the holy place 'the abomination that causes desolation,' spoken of through the prophet Daniel—let the reader understand—then let those who are in Judea flee to the mountains. Let no one on the roof of his house go down to take anything out of the house. Let no one in the field go back to get his cloak. How dreadful it will be in those days for pregnant women and nursing mothers! Pray that your flight will not take place in winter or on the Sabbath. For then there will be great distress, unequaled from the beginning of the world until now—and never to be equaled again. If those days had not been cut short, no one would survive, but for the sake of the elect those days will be shortened. At that time if anyone says to you, 'Look, here is the Christ!' or, 'There he is!' do not believe it. For false Christs and false prophets will appear and perform great signs and miracles to deceive even the elect—if that were possible. See, I have told you ahead of time.
"So if anyone tells you, 'There he is, out in the desert,' do not go out; or, 'Here he is, in the inner rooms,' do not believe it. For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man. Wherever there is a carcass, there the vultures will gather.
"Immediately after the distress of those days
" 'the sun will be darkened,
and the moon will not give its light;
the stars will fall from the sky,
and the heavenly bodies will be shaken.'
"At that time the sign of the Son of Man will appear in the sky, and all the nations of the earth will mourn. They will see the Son of Man coming on the clouds of the sky, with power and great glory. And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other.
"Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. Even so, when you see all these things, you know that it is near, right at the door. I tell you the truth, this generation will certainly not pass away until all these things have happened.
Heaven and earth will pass away, but my words will never pass away.
"No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father. As it was in the days of Noah, so it will be at the coming of the Son of Man. For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man. Two men will be in the field; one will be taken and the other left. Two women will be grinding with a hand mill; one will be taken and the other left.
"Therefore keep watch, because you do not know on what day your Lord will come. But understand this: If the owner of the house had known at what time of night the thief was coming, he would have kept watch and would not have let his house be broken into. So you also must be ready, because the Son of Man will come at an hour when you do not expect him.
As you can see, Jesus is not referring to the current generation, but to the generation in which the signs are fulfilled.
Matthew 26:64 Jesus saith unto him, Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
Matthew 26:62-64 Then the high priest stood up and said to Jesus, "Are you not going to answer? What is this testimony that these men are bringing against you?" But Jesus remained silent.
The high priest said to him, "I charge you under oath by the living God: Tell us if you are the Christ, the Son of God."
"Yes, it is as you say," Jesus replied. "But I say to all of you: In the future
you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven." In your lifetime
and in the future
could, but do not neccesarily, mean the same thing. They certainly didn't here.
Mark 9:1 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.
The next passage is the tranfiguration of Jesus in all His glory
Mark 13:30 Verily I say unto you, that this generation shall not pass, till all these things be done.
Mark 13 is very similar to Matthew 24. The same explanation applies here.
Mark 14:62 And Jesus said, I am: and ye shall see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
This has the same explanation as Matthew 26:64
Luke 9:27 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.
Jesus was speaking privately to the disciples, and the very next passage is the transfiguration!
Luke 21:32 Verily I say unto you, This generation shall not pass away, till all be fulfilled.
Once again, Jesus is referring to the generation in which the signs are fulfilled.
Isn't it amazing what you can make scripture look like it is saying when you take it out of context?
