There is a video
here which lists several NT passages that indicate that the followers of Jesus expected him to return in their lifetime, many of which don’t hinge on how “generation” is defined.
… this generation shall not pass…
Matthew 24:34
Amen I say to you, that this generation shall not pass, till all these things be done.
Mark 13:30
Amen I say to you, that this generation shall not pass, until all these things be done.
Luke 21:32
Amen, I say to you, this generation shall not pass away, till all things be fulfilled.
Matthew 23:36
Amen I say to you, all these things shall come upon this generation.
… shall not taste death…
Matthew 16:28
Amen I say to you, there are some of them that stand here, that shall not taste death, till they see the Son of man coming in his kingdom.
Mark 9:1
And he said to them, “Truly I tell you, some who are standing here will not taste death before they see that the kingdom of God has come with power.”
Luke 9:27
But I tell you of a truth: There are some standing here that shall not taste death, till they see the kingdom of God.
Caiphas, the high priest, shall see the return of Jesus in the clouds.
Matthew 26:64
Jesus saith to him: Thou hast said it. Nevertheless I say to you, hereafter you shall see the Son of man sitting on the right hand of the power of God, and coming in the clouds of heaven.
Mark 14:62
And Jesus said to him: I am. And you shall see the Son of man sitting on the right hand of the power of God, and coming with the clouds of heaven.
Individual examples
Matthew 10:23
And when they shall persecute you in this city, flee into another. Amen I say to you, you shall not finish all the cities of Israel, till the Son of man come.
(The author of the video points out that with a such a small area as Israel, that going to each city could be done very quickly.)
1 Corinthians 7:29
This therefore I say, brethren; the time is short; it remaineth, that they also who have wives, be as if they had none;
1 Thessalonians 4:16-17
Then we who are alive, who are left, shall be taken up together with them in the clouds to meet Christ, into the air, and so shall we be always with the Lord. Wherefore, comfort ye one another with these words.
1 Peter 4:7
But the end of all is at hand. Be prudent therefore, and watch in prayers.
James 5:8-9
Be you therefore also patient, and strengthen your hearts: for the coming of the Lord is at hand.
Grudge not, brethren, one against another, that you may not be judged. Behold the judge standeth before the door.
This may be a reference to this passage in Mark 13:29
So you also when you shall see these things come to pass, know ye that it is very nigh, even at the doors.
Assuaging fears that Jesus has not returned
2 Peter 3:9
The Lord delayeth not his promise, as some imagine, but dealeth patiently for your sake, not willing that any should perish, but that all should return to penance.
The author of the video also pointed out that the Bible says to ignore anyone whose prophecy does not come true, as it’s not from God:
Deuteronomy 18:22
Thou shalt have this sign: Whatsoever that same prophet foretelleth in the name of the Lord, and it cometh not to pass: that thing the Lord hath not spoken, but the prophet hath forged it by the pride of his mind: and therefore thou shalt not fear him.
If anyone is interested in seeing the whole series,
here’s part 1 which is a summary of the argument. Part 2 is the one I linked to above. Part 3 is
here. Part 4, which includes arguments against preterism, is
here. The final part, which argues against futurism as well as against defining “generation” as “people” or “nation” is
here.
