The WTS often quotes Matt 24:44:
"On this account YOU too prove yourselves ready, because at an hour that YOU do not think to be it, the Son of man is coming."
Of course the application here is that Christ is coming to bring judgment on the earth and end the current "system of things".
For example:
*** w05 1/15 p. 20 par. 19 Foregleams of God’s Kingdom Become a Reality ***Do you want to be among those who will stand in awe of the victorious Son of God? Then continue to nourish your faith and to ‘prove yourself ready, because at an hour that you do not think to be it, the Son of man is coming.’—Matthew 24:43, 44.
But looking at the context of the verse, what event is signified by Jesus' reference to his coming (greek: erchomai)?
Check it out in context (Matt 24:44-51):
Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh (erchomai).
Who then is a faithful and wise servant, whom his lord hath made ruler over his household, to give them meat in due season? Blessed [is] that servant, whom his lord when he cometh (erchomai) shall find so doing. Verily I say unto you, That he shall make him ruler over all his goods. But and if that evil servant shall say in his heart, My lord delayeth his coming (erchomai); And shall begin to smite [his] fellowservants, and to eat and drink with the drunken; The lord of that servant shall come (heko)in a day when he looketh not for [him], and in an hour that he is not aware of, And shall cut him asunder, and appoint [him] his portion with the hypocrites: there shall be weeping and gnashing of teeth.
Interestingly, in the portion of this passage that describes the "faithful servant", the WTS says that THIS time, Christ refers to "coming", not in the sense of returning to destroy the current system, but to describe the onset of his invisible "presence" in 1914, which, interestingly, is only cryptically perceptible to the "faithful servant" and imperceptible to the unfaithful servant.
Isn't this a confusing way for Christ to speak to his disciples? In fact, in reading Matt 24 with the WTS assumptions in place, one must switch back and forth in such a manner between these two different definitions of Christ's "coming".
In typical fashion, the WTS reduces scripture to a lot of disconnected verses with disconnected meanings.
A straight reading of the passage could be paraphrased this way:
"Look, disciples. I'm coming back, but I won't say exactly when, so be ready at all times. So you gotta ask yourselves one thing. Are you going to be like that faithful servant who takes care of the master's household as if the master could come back at any minute, or are you going to be like that slacker servant who figures he's got enough time before the master returns to throw a big kegger, eat up all the food, and give the other servants a few good beatings? You can count on his master coming back when he least expects it to catch him in the act. When that happens, it ain't gonna be pretty. Now you tell me, which one of these guys is the master gonna reward?"
