Just because Jesus told the people of his day that no one knows the day and hour does not mean that we won't know when it is near even within a few days. He gave us signs and even said that he would return AFTER the tribulation of the last days...so to be specific maybe we won't know the exact day and hour but we will know within a few days. You asked why give signs. So we will know when he is return is near. Is Jesus coming back tomorrow? No. Is Jesus coming back within a few years? No. Don't believe me? Just watch and see.There are plenty of false 'Christs' in our day such as José Luis de Jesús whose followers tattoo 666 to themselves, Maitreya, and Jesus of Siberia who has written another of many false gospels. False prophets such as Joseph Smith and Benny Hinn have lead people astray.
Prophecy picks up faster each day, more so since the rebirth of Israel.
The United States has become a nation of promiscuity and simply puts Christianity on as a guise.
Rumors of War happen now, more and more this past century and during this current NK Missile crisis. We now have possibilities of nuclear wars. (Zechariah 14:12?)
Is it true that fault lines have been found at the mountains that are supposed to split at the feet of the LORD?
Or is this just normal every day findings?
Since Jesus said that no one knows the day or hour, does that mean watching for signs is a redundant thing to do? Why give signs?
There will come a time when one can know pretty close...
Rev 11:3 And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
Rev 11:7 And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them.
Rev 11:8 And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified.
Rev 11:9 And they of the people and kindreds and tongues and nations shall see their dead bodies three days and an half, and shall not suffer their dead bodies to be put in graves.
Rev 11:10 And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth.
Rev 11:11 And after three days and an half the Spirit of life from God entered into them, and they stood upon their feet; and great fear fell upon them which saw them.
Rev 11:12 And they heard a great voice from heaven saying unto them, Come up hither. And they ascended up to heaven in a cloud; and their enemies beheld them.
Rev 11:13 And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand: and the remnant were affrighted, and gave glory to the God of heaven.
Rev 11:14 The second woe is past; and, behold, the third woe cometh quickly.
Rev 11:15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
Now this leaves us knowing within 3-1/2 days. are the 3-1/2 days their bodies lie in the streets contained within the 1260 days? Or are they the 3-1/2 days immediately after?
