A Pre-Trib rapture is biblically correct. The rapture itself has been in the bible all along, notwithstanding assertions that it was a made-up doctrine from the 1800s. And the rapture's timing happening prior to the Tribulation has always been biblically evident too. It was only lately that man began to shy away from the clear teaching of this and muddy the waters to the extent that people now are hesitant to be dogmatic about it- so much so that they think they are being pious to show uncertainty. Look at Mr Greene's statement on the subject (I kept his exact emphases):
The Great Tribulation has nothing to do with the church; the Church will not enter or go through any part of that terrible time. Any preacher or teacher who suggests that the bride of Christ will be subjected to any part of the reign of the Antichrist is definitely wrongly dividing the Word of Truth. God pity the preacher who will accuse Jesus of allowing the Antichrist to reign over His bride-and the Church IS the bride of Christ!
We have the blessed promise, "Because thou hast kept the word of my patience, I will also keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell on the earth." (Revelation 3:10).
In the writings of Paul we are promised. "For God hath not appointed us to WRATH, but to obtain salvation by our Lord Jesus Christ." (1 Thess. 5:9). The Great Tribulation has to do with the nation of Israel, not with the Church.
If the Church were to enter or go through any part of the tribulation, believers would be commanded to watch for Antichrist, not for THE CHRIST. We would be commanded to watch for the great tribulation, not to wait for God's Son from heaven. (1 Thess. 1:10).
