Which is altogeather different from the parousia, ie. Second Coming. Jesus said he will return in the future and that no one knows the day or hour. The Olivet discourse as related by Luke indicates this event would be far off and people would lose faith in the interim. Thus, there in nothing wrong in speaking of the future retun and judgment of Christ, or the great tribulations which will accompany and precede it, it is just wrong to set dates. It could be in a couple of years or it could be another 1000 years.
That is the point. When Jesus and the other NT writers (esp. John in Revelation) spoke of things as "near" or "at hand," they were not speaking of the Second Coming, or events related to the Second Coming. They were speaking of the events related to AD70 that came upon "this generation."
Folks who fail to differentiate this fact from Scripture end up looking foolish.
