Secret Rapture seems to be one of the greatest deception in churches today. One of the famous verses often quoted is,
Luke 17:34 “I tell you, in that night there will be two [men] in one bed: the one will be taken and the other will be left.
Luke 17:37 And they answered and said to Him, “Where, Lord?” So He said to them, “Wherever the body is, there the eagles will be gathered together.”
1Thess 4:17 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.
1Thess 4:16 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.
Acts 1:11 who also said, “Men of Galilee, why do you stand gazing up into heaven? This [same] Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven.”
1Thess 5:2 For you yourselves know perfectly that the day of the Lord so comes as a thief in the night.
2Pet 3:10 But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up.
Peter clears up with much clarity. There is no pre-trib secret rapture. It is a false doctrine which does not prepare the flock for the great tribulation.
