There are many People who (rightly or wrongly so) feel they have been appointed or called of God to be like 'Watchmen on the Walls' in these last days;
Isaiah 62:6 - I have set watchmen upon thy walls, O Jerusalem, which shall never hold their peace day nor night: ye that make mention of the LORD, keep not silence,
&
Isaiah 21:6 - For thus hath the LORD said unto me, Go, set a watchman, let him declare what he seeth.
last but not least;
Ezekiel 33:6 - But if the watchman see the sword come, and blow not the trumpet, and the people be not warned; if the sword come, and take any person from among them, he is taken away in his iniquity; but his blood will I require at the watchman's hand.
Ezekiel 33:7 - So thou, O son of man, I have set thee a watchman unto the house of Israel; therefore thou shalt hear the word at my mouth, and warn them from me.
I mean, the Bible even speaks of 'scoffers' in these last days. so while I agree No Man knows the EXACT hour of His coming, I'm hesitant to say 'all' are false Prophets or a waste of time.. I mean Noah was a Prophet that forewarned of coming destruction and only eight followed Him into deliverance from God's judgment.. Christ admonishes us to 'know' and 'discern' the signs of the 'times' when His return draws near.. He tells us when we see these things begin to happen to 'lift up our heads because our redemption draweth nigh" (Luke 21:28)... and He wants us to share this with others so they too can know Him and be ready.
If Scripture teaches us anything about God (Especially the OT) it teaches us that our God is a God of 'seed time' and 'Harvest'.. I see 'seed time' ending soon, (tho' I'll continue to sow faithfully until that day, however I 'feel' in my Spirit that the great Harvest is coming soon). Sooner than many or most think even. This is 'my' burden perhaps, if God burdens as some say He does not.. I beg to differ. The Holy Spirit grieves and moans within me many times... I don't question I just receive.
The scripture below even gives me the 'hope' that we're to 'look' for these such things.. such as the 'times' of His appearing;
1Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless. - 2 Peter 3:14
I see 'date setters' as just that, date setters. Many have sincere hearts & motives. Many people I'm aware are sincerely 'wrong' but God sees our Hearts...
I'm not offended, but I do 'watch' for His coming, and many times I read these sites because if they are in fact of the Devil I want to 'know' how he's operating also so that I can warn people of his wiles also...
Christ didn't suffer Demons well either, He cast them out at every opportunity.
As much as I'd like to be able to.. I'm not 'qualified' to judge the hearts or motives of the People behind many of these Sites, and I believe 'one' of them eventually is going to be right.. just as Noah was right ... that's 'why' I post them.. so we can discuss them as the Bible instructs... There is Wisdom in the multitude of counsel.
He replied, "Go your way, Daniel, because the words are closed up and sealed until the time of the end.- Daniel 12:9
and;
In that day the deaf will hear the words of the [previous shut up & sealed] scroll, and out of gloom and darkness the eyes of the blind will see. - Isaiah 29:18
