How does Jesus say he will return? Not in some secret rapture like you have claimed.
No mention of a secret rapture here:
Mt 24:29-30
Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
No mention of a secret rapture here either
Mt 26:64
Jesus saith unto him, Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
No mention of a secret rapture here either
1:9-11 And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight. And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
No mention of a secret rapture here either
Rv 1:7 Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen.
In short, no where does Jesus say He will return in some secret gathering before the second coming. The pretrib rapture is a big mess of goobly gook. It's not in scripture. It's only in the minds of those who have been taught by false teachers.
