Q - Why is the post tribulation rapture false teaching?

A - Because the word of God clearly teaches a Pre-tribulation Rapture.

The true faithful Church will be caught up and away FROM the earth before the destruction begins.

It's absurd to say that Jesus is going to return FOR His saints, while at the same time COMING to establish His Millennial Kingdom. Why would Jesus remove us from the earth if he's coming to the earth at the same time? Come on now God gave you a brain use it!

Common sense is evident in Paul's message to the church, to "COMFORT one another" If the Church expects to go through horrible atrocities (which we can't begin to imagine during the Tribulation), his words wouldn't be comforting but something to be feared and certainly not a "blessed hope".

Remembering God didn't destroy the wicked in Noah's day until Noah and his family were all safely aboard the ark.

Not one drop of rain fell until Noah and his family was on the ark, God shut the door. THEN the rains fell and the wicked were utterly destroyed.

Genesis 19:22
Haste thee, ESCAPE thither; for I cannot do any thing till thou be come thither.

These words were spoken by the angel whom God had sent to reign down fire and brimstone upon Sodom and Gomorrah.

Will God have a change of Heart for the church? NO God never changes. The Body of Christ will be translated (removed) away from this sin-cursed world before the Tribulation.

Hebrews 11:5.
By FAITH Enoch was translated (removed) that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God. Do you want to be removed before the tribulation starts? Then please God by living right and have faith in him and you will be removed just like Enoch.

This Scripture tells us where 'the Bride' will always be found: (after the pre-tribulation rapture)

1 Thessalonians 4:17
Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air; and SO SHALL WE EVER BE WITH THE LORD.

The 'Philadelphia Christians' (overcomers) will be The Raptured Bride, and the 'Laodicea Christians' (lukewarm and blackslidden Christians will be left behind)

This Scripture tells us what to expect after 'The Bride' is raptured to Heaven:

Revelation 13:6-7
He (the antichrist) opened his mouth to blaspheme God, and to slander His name and His dwelling place and those WHO LIVE IN HEAVEN (The Bride). He was given power to make war against THE SAINTS (The lukewarm Church left-behind) and to conquer them. And he was given authority over every tribe, people, language and nation.

This Scripture gives advice to those left-behind:

Revelation 13:10
This calls for patient endurance and faithfulness on the part of the saints.

How about the Day of the Lord vs. the Day of Christ?

The Day of the Lord is literally referring to a span of time and not any one day. The Day of Christ (for the first time) is mentioned in 2 Thessalonians 2:2, "That ye be not soon SHAKEN in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand." "The Day of Christ" begins with the Rapture of the saints called up, to be with Christ. The Day of Christ will continue throughout the Millennium. The Day of Christ pertains to the redeemed and their rewards or judgments as BELIEVERS.

The Day of the Lord has to do with the UNSAVED only, and the miseries coming upon them. "The Day of the Lord" (1Thessalonians 5:2) refers to Christ's universal dealings with the ungodly, in judgment, in preparation for His eternal Kingdom on earth. Glory to God He is not speaking of the church here.

To the people that insists that they will be here for the tribulation I agree with them that THEY will be here as for me and my family we will be safe with Jesus because by grace we are saved through faith and by faith we will be taken in the pre tribulation rapture. Because of their lack of faith in Jesus Christ and unwillingness to believe the truth from the word of God THEY will be left behind as they deserve to be tested by fire.

People that do not believe God will not keep his word insults Almighty God by refusing to believe His Word. In doing so, they are saying that God isn't worth trusting -- that He is a liar and a deceiver. The Bible says, "He who does not believe God has made Him a liar," (1 John 5:10). It also says, "Beware, brethren, lest there be in any of you an evil heart of unbelief. . ." (Hebrews 3:12). Martin Luther said, "What greater insult . . . can there be to God, than not to believe His promises."

God said "I will never leave you or forsake you". Believe it, trust it, live by his word and you will never see one single day of the coming tribulation.
