I speak from a Seventh Day Adventist perspective.
The scriptures used to justify post-tribulation rapture are often the same scriptures used to justify pre-tribulation rapture. The main difference being -- we do not believe those who are Jewish will be treated any differently from other nations (Gal 3:28-29), and that all Christians make up what is referred to as 'Spiritual Israel'.
But Jerusalem which is above is free, which is the mother of us all. (Gal 4:26)
And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God. (Gal 6:16)
With this in mind, then all scripture that refer to Israel in the last days refer actually to all Christians.
Alas! for that day is great, so that none is like it: it is even the time of Jacob's trouble, but he shall be saved out of it. (Jer 30:7)
The time of Jacob's trouble is for all Christians. They "shall be saved out of it" because God will deliver them from those who persecute them, and they will not perish. The whole premise of Jacob's night of wrestling was that he suffered through the trial and was then saved from Esau by his faith. Likewise, Christians in the last days will suffer persecution (Rev 13:17), they will cry day and night to God for deliverance, and God will save them by their faith.
And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book (Dan 12:1).
Again, God's people, Christians, will be delivered. This is at the time of trouble and not before it. Christians in the last days are Daniel's people because there is no distinction now between Jews and Gentiles, only believers and non-believers.
For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened. (Matt 24:21-22)
Elect refers to Christians not just converted Jews. (See also Col 3:12). The elect go through the great tribulation, but it is shortened for their sake.
The above, plus the lack of scriptures that depict two separate translation events or secret rapture, points strongly to Post-tribulation rapture.
Rapture, in this case, is simply the translation of living at Jesus' second coming, which is well backed by scripture. (1 Cor 15:51-52, Matt 24:31, 1 Thes 4:16-17)
The only difficult scripture is Matt 24:40-42, which we interpret as figurative, since no one will be buying or selling in the last days who have victory over the mark of the beast (Rev 20:4), let alone working.
God's church will live through the great tribulation, but they will not be harmed by the plagues, and will be delivered.
And not only so, but we glory in tribulations also: knowing that tribulation worketh patience; (Rom 5:3)
