First off, there is no Pre-Trib Rapture of the church. I hope everyone understands that this teaching is a lie from Satan as there is nothing in the Bible that discusses Jesus returning Before the Tribulation, coming twice or taking the church to heaven.
That said, yes, the end is near. I believe that within 20 years we will either be past the Tribulation or deep into it. This is based on 70 years from when Israel became a nation or from when Jerusalem returned to Israeli control. So add 70 years to 1948 or 1967 and you get 2018 or 2037 which Jesus himself said in Mat 24:34 that "this generation shall not pass until all these things take place." A generation is 70 years as defined by David in Psalm 90.
I like the 2037 date better because it corresponds better to things going on today. First we have the 2,000 year anniversary of Christ's resurrection coming up in April 2033. 4,000 years from Adam to Christ, 2000 years from Christ to the end. Then we have asteroid Apophis due to come on Good Friday, April 13, 2029 with a 2.3% chance of hitting us (the highest threat ever recorded by NASA). If it misses us then it comes back 7 years later on Easter Sunday. This could be the mountain thrown into the sea spoken of in Revelation.
