So you have Scripture that contradicts the Scripture in the article and supports your assertion that 1 Thessalonians 4:12-18 is false?
One of the problems with the pre-trib rapture view is that is a modern, Western European/American invention, that only works in Western culture.
Scripture is for all men, in all times.
One of the problems with the pre-trib rapture view is that people focus on the rapture...the easy escape from suffering...Christians all over the world may be put through the meat grinder of suffering, but they expect to be raptured out of the same in America. Look those Christians in the face, and tell them their tribulations do not count.
If your focus is on the rapture over the return of the Lord Jesus Christ, your focus is on the wrong thing.
Scripture is it's own interpreter; it's own dictionary. Take 1 Thessalonians 4:12 to 18 and test it by Scripture. For a start, for every redeemed,regenerated Christian, the Lord Jesus has already come, and we live in His presence. Eph 2: But God, being rich in mercy, because of the great love with which He loved us, even when we were dead in our transgressions, made us alive together with Christ (by grace you have been saved), and raised us up with Him, and seated us with Him, in the Heavenly places, in Christ Jesus...
To consign these Scriptures to some future, one time, fabulous event robs believers of their blessing,comfort,and encouragement for the Right Now. Instead of focusing the rapture Christian should be sharing the Gospel of salvation with as many as possible.
For God so loved the world, that whosoever believeth in Him should not perish, but have everlasting life. John 3:16
