The Blessed Hope

The hope of a pre-trib rapture is not the blessed hope; it is a false hope. No one should lose the blessed hope (Titus 2:13) when the rapture doesn't happen before the tribulation. No one should lose the hope even if they are at the point of death in the great tribulation, for our hope for eternal life in Jesus Christ (Titus 1:2, 2:13, 3:7) goes beyond any suffering in this life and any dread of death (Philippians 1:21-23, 1 Corinthians 15:19, John 12:25, Revelation 2:10, Hebrews 2:15).

"In hope of eternal life"
"That blessed hope"
"The hope of eternal life"
(Titus 1:2, 2:13, 3:7).

Note that tribulation and hope aren't opposed to each other:

"We glory in tribulations also: knowing that tribulation worketh patience; And patience, experience; and experience, hope" (Romans 5:3-4).

"Rejoicing in hope; patient in tribulation" (Romans 12:12).

"If in this life only we have hope in Christ, we are of all men most miserable" (1 Corinthians 15:19).

"For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake" (Philippians 1:29).

"For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us" (Romans 8:18).

"For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory" (2 Corinthians 4:17).

"Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you: But rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy" (1 Peter 4:12-13).

Looking For Antichrist Instead Of Christ?

Note that someone who believes the rapture is after the tribulation isn't looking for the Antichrist instead of Christ, just as a pregnant woman isn't looking for birth pangs instead of the birth of her child, but they know what must come first (1 Peter 4:12-13). We Christians must go through the reign of the Antichrist (Revelation 13:7-10, 14:12-13). Christ's coming to gather us together must destroy the Antichrist (2 Thessalonians 2:1-8, compare Matthew 24:29-31).

Note that a woman's preparations for a birth cannot be separated from her care about the birth of her child. Have you ever heard someone scolding a pregnant woman for going to the doctor or to birth classes, saying: "You don't care about your child or its birth; you're only thinking about the birth pangs you'll have before it's born"?

*******
Scoffers?

Note that someone who believes the rapture is after the tribulation at the 2nd coming of Jesus (Matthew 24:29-31; 2 Thessalonians 2:1-8) in no way scoffs at his 2nd coming (2 Peter 3:2-4).

*******
No Comfort?

Note that neither 1 Thessalonians 4:13-18 nor 1 Thessalonians 5:10-11 says anything regarding the timing of the rapture in relation to the tribulation, for tribulation and comfort aren't opposed to each other:

"I am filled with comfort, I am exceeding joyful in all our tribulation" (2 Corinthians 7:4).

"Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God. For as the sufferings of Christ abound in us, so our consolation also aboundeth by Christ. And whether we be afflicted, it is for your consolation and salvation, which is effectual in the enduring of the same sufferings which we also suffer: or whether we be comforted, it is for your consolation and salvation. And our hope of you is stedfast, knowing, that as ye are partakers of the sufferings, so shall ye be also of the consolation" (2 Corinthians 1:3-7).

"To comfort you concerning your faith: That no man should be moved by these afflictions: for yourselves know that we are appointed thereunto. For verily, when we were with you, we told you before that we should suffer tribulation" (1 Thessalonians 3:2-4).

In 1 Thessalonians 4:13-18 and 1 Thessalonians 5:10-11, Paul meant we're to comfort each other that we'll see our departed loved ones again, and that even if we die ourselves, we will still live with Jesus: "I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him... Wherefore comfort one another with these words" (1 Thessalonians 4:13-14, 18); "Whether we wake or sleep, we should live together with him. Wherefore comfort yourselves" (1 Thessalonians 5:10-11).

*******
No Joy?

Note that tribulation and joy aren't opposed to each other:

"I am exceeding joyful in all our tribulation" (2 Corinthians 7:4).

"Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you: But rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy" (1 Peter 4:12-13).

*******
No Peace?

For Christians, peace of mind and tribulation are not mutually exclusive:

"These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world" (John 16:33).

*******
Tribes Of The Earth Mourning?

While Matthew 24:30 and Revelation 1:7 say that at Jesus' coming "then shall all the tribes of the earth mourn," Matthew 24:30-31 refers to the gathering together of us believers when Jesus comes "in his glory," and surely then we will not be mourning like the unbelievers will be, for "when his glory shall be revealed, ye may be glad also with exceeding joy" (1 Peter 4:13).
