I agree with this. On another note,you do recognize that God ALLOWED the disciples(church)to believe that Jesus "could"return before the death of John the apostle. Jesus did not say directly that He would return before the death of John but His statement,"what if I will that he tarry till I come", was enough to make the church believe that Jesus would "probably"come before the death of John. Conclusion,God wanted the first church to believe that Jesus could return in their lifetime although it was not in the plan of God for it to happen as we can see today.
No!!! i think that God clearly killed that concept that was running wild in that day with 2 thess 2
v2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as
that the day of Christ is at hand.
3 Let no man deceive you by any means:
for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
5 Remember ye not, that, when I was yet with you, I told you these things?
6 And now ye know what withholdeth that he might be revealed in his time.
7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
8
And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and
shall destroy with the brightness of his coming:
The destruction of the son of perdition comes with the presence of the lord, and the return of the lord comes after the falling away. There should be no confusion on this. it may be hard to define the falling away, but the revelation of the son of perdition, and his destruction is pictured three times in the OT, and has not been fullfilled as they also lead to the day of the lord.
Here is just one sample.
Eze 28v16
By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
17 Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kings,
that they may behold thee.
18 Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will
I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee.
