All my life I have heard preachers and others say that we are living in the endtime, the last generation before the return of Christ.
There were other people who had heard that same thing about 2,000 years ago and that THEY were that chosen endtime generation.
1Pet. 2:9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
Yes, later translations say "race" instead of generation but since Christendom is a mixture of more than one race, the word cannot mean "race" but literally, "generation". That they were the chosen generation is confirmed by Paul.
Eph 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
Eph 1:5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will,
So, there you have it. THEY were the chosen and PREDESTINED endtime generation when all things written would be fulfilled.
Luke 21:22 For these be the days of vengeance, that all things which are written may be fulfilled.
It was the same days of vengeance promised to the scribes and Pharisees - in their days, in their time 2,000 years ago.
Matt. 23:35 That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar.
Matt. 23:36 Verily I say unto you, All these things shall come upon this generation.
Sometime after that 40 year generation came to a close and . . . no return of Jesus . . . people began to ask a very legitimate question.
2Pe 3:4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.
And, it's been excuses ever since, beginning with the thousand years as one day thing. A thousand years may be the same as one day to a god but to the people who were promised that it would be in their chosen generation it's a lot longer.
