JESUS mentioned a number of times His return to earth, and His people will be taken with Him to Heaven!
"Then they will see the Son of Man coming in the clouds with great power and glory. And then He will send His angels, and gather together His elect from the four winds, from the farthest part of earth to the farthest part of heaven." Mark 13:26-27
"But of that day and hour no one knows, not even the angels of heaven, but My Father only. But as the days of Noah were, so also will the coming of the Son of Man be. For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and did not know until the flood came and took them all away, so also will the coming of the Son of Man be." Matthew 24:36-39
"For the LORD Himself will descend from Heaven with a shout, with the voice of an archangel, and with the trumpet of GOD. And the dead in CHRIST will rise first. Then we who are alive and remain shall be caught up together with them in the clouds to meet the LORD in the air. And thus we shall always be with the LORD." 1 Thessalonians 4:16-17
