The Church will be here until the "end of the age"

Matthew 28:20 "I am with you always, to the very end of the age."

Matthew 13:39 "the harvest is the end of the age, and the harvesters are angels."

Matthew 24:3 "What will be the sign of your coming and of the end of the age?"

Matthew 24:6 "...such things must happen, but the end is still to come."

Matthew 24:13 "he who stands firm to the end will be saved."

Matthew 24:14 "And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come."

Matthew 24:15-28 describes the great tribulation

Matthew 24:29 "Immediately after the distress(tribulation) of those days "the sun will be darkened, and the moon will not give its light; the stars will fall from the sky, and the heavenly bodies will be shaken."

That verse describes the sign of the end of the age. The Church is still here. In verses 30-31 the Church is raptured.
