The Church will be present on earth to witness the great tribulation, and second coming of Jesus Christ in the heavens, just as Luke 21:25-28 "Clearly" teaches below, there will be no (Pre-Trib Rapture) as dispensationalism falsely teaches, dont be deceived
Luke 21:25-28KJV
25 And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;
26 Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.
27 And then shall they see the Son of man coming in a cloud with power and great glory.
28 And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh.

In Luke 21:8-35 Jesus describes the tribulation, then says THIS important statement about the tribulation:
Luk 21:36 Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
Those Christians who are worthy, will escape all those things in the great tribulation, not go through them.
