I would like to point out that Jesus Christ of Nazareth said, "Assuredly, I say to you, there are some standing here who shall not taste death till they see the Son of Man coming in His kingdom" (Matthew 16:28, NKJV). These people were physically standing there. This specific assurance to some of His contemporary hearers makes the Futurist view difficult to reconcile, as it suggests the fulfillment of the kingdom's arrival was imminent for that first-century group, unlike the Partial Preterist view which acknowledges an early fulfillment in A.D. 70 actually within that generation , like He said.
But let's not stop there. Historically, when " this generation " is used, it always pertained to the contemporary audience. Here are some examples:
-"Then the LORD said to Noah, 'Come into the ark, you and all your household, because I have seen that you are righteous before Me in this generation.'" (Genesis 7:1)
“Surely not one of these men of this evil generation shall see that good land, of which I swore to give to your fathers, except Caleb the son of Jephunneh and Joshua the son of Nun.” Deuteronomy 1:35
Now let's look at the wording for a future generation. The most common ways the Bible refers to a generation that will exist in the future are. "a generation to come" or "the next generation"", These phrases clearly look forward, signifying a group of people who will live later.
* Psalm 78:4 (NKJV): "We will not hide them from their children, telling to the generation to come the praises of the LORD, And His strength and His wonderful works that He has done."
* Psalm 102:18 (NKJV): "Let this be recorded for a generation to come, so that a people yet to be created may praise the LORD."
In conclusion:
The phrase "this generation" means only the people standing there with Jesus, receiving a prophecy of an imminent judgment , like the destruction of Jerusalem in A.D. 70. This limits the prophecy to their lifetime and has no correlation with the future. The New Testament would use the term "age to come" for distant events and generations rather than that generation, past or this generation current.
