That is the word of Holy Scripture and not my suggestion.
Listen to the Apostle: “We which are alive, and remain unto the coming of the Lord.”
The Apostle said that for his generation.
He said it not under his own mistaken idea as the Chicago department of “sacred literature” would suggest, but under the inspiration of the Holy Spirit of the Holy God.
Paul as a mere man might make mistakes just as the modern theological professor not infrequently does.
The Holy Spirit speaking through Paul could not make a mistake Himself, neither could it be possible for Paul under the direction of the Holy Spirit to make a mistake.
Paul was led by the Holy Spirit to believe it possible the Son of God might come in his day.
What Paul under inspiration said for his generation, he said for our generation.
He said it for you and for me.
Because no man knows the hour when the Lord will come it might be in your hour and my hour.
