First of all if people are as excessively eager and overly enthusiastic as to believe in prophethood of Mr Isawtheilghminister, they will be able to accept whatsoever justification and nobody will be able to help here, that's just a treacherous human nature that tends to think wishfully rather than correctly, moreover if a seed of a very strong temptation sowed deeply in our hearts to find Somebody, a Guru, a Teacher, an Ayatollah, a Fuhrer etc. - their names are legion - is left unchecked, then trouble comes and even if this guru empties one’s all bank accounts or commits a murder, his adept will still find a ready justification, plenty of them, as a matter of fact. 

As to that Mr Isawthel Minister guy’s self-justifications, they are partially true, for the early Christians. Even the Apostles, considered the Second Coming as something imminent, even in their own life's time; but even they, the apostles evolved in this perception.

Of course already Paul does not believe that Christ will come in his lifetime.

**2 Tim 4:6-8** ([NASB][1])

> <sup>6</sup> For I am already being poured out as a drink offering, and the time of my departure has come. <sup>7</sup> I have fought the good fight, I have finished the course, I have kept the faith; <sup>8</sup> in the future there is laid up for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day; and not only to me, but also to all who have loved His appearing.

In the consciousness of Church this time has become gradually more apophatic, while the Church teaching about the end concentrated not on the end of history, but the end of each human life, which, as a matter of fact, is a mini-end of the world, for this person, because his historical world ends indeed with his physical death. So the logic is: do not bother yourself about the Second Coming that only God knows, "this thing is not for you to know" (Acts 1:7), but bother about what you know, i.e., your own sinfulness and your task to get liberated from it through life in Christ, in prayers and good deeds. 

But when a person returns to this first-Christian sentiments, as if they were not changed and balanced by the living thousand-years’ history of Church, and alarmingly prophesizes about the end of history and imminent coming of Christ, like Jehovah Witnesses founder Russel so many times vainly prophesized about coming of Christ, one can most certainly smell a blatant charlatanism in all that.
