There are many signs of the End Times, before the 7 Year world tribulation period. However the biggest signs:

- FALSE CHRISTS/MESSIAHS will point the way to life other than Yeshua being the only way – e.g. Muhammad, Joseph Smith (Matt. 24:5, Mark 13:6, Luke 21:8) - WARS & RUMORS OF WAR (Matt. 24:6, Mark 13:7-8, Luke 21:9-10) - FAMINE, PESTILENCES, EARTHQUAKES VARIOUS PLACES WILL INCREASE (Matt. 24:7, Mark 13:8, Luke 21:11) - GLOBAL PERSECUTION OF YESHUA’S (JESUS) FOLLOWERS (Matt. 24:9-10, Mark 13:9-13, Luke 21:12-19, 2 Tim. 3:1-5) - WHILE THE GOSPEL IS PREACHED TO ALL NATIONS (Mark 13:10) - FRIENDS, FAMILY & PARENTS will betray each other (Luke 21:16) - FALSE PROPHETS DECEIVE MANY e.g. Media (Matt. 24:11) - DISREGARD OF GOD’S LAW – e.g. Calling evil good and good evil (Matt. 24:12) - SIGNS IN THE SUN, MOON & STARS AND THE WAVES AND SEA ROARING (Luke 21:11, 25) - HEARTS OF MANY WILL FAIL FOR FEAR OF THESE THINGS WHICH COME ON THE EARTH (Luke 21:26) - 10 KINGS WILL START TO BE FORMED BEFORE THE LAST EMPIRE STARTS (Dan. 2:41-42; 7:24). - 11 TEMPLE WILL START AND BE FUNCTIONING (Rev. 11:1-3) as the sacrifices will continue until the Beast enters the Temple after 3 ½ years (Dan. 12:11). It will be built on mount Moriah (2 Chr. 3:1), where the Dome of the Rock in Jerusalem is today. It might be the Ezekiel Temple as it would be operational during the Millennium (Ezek. 40).
