Not true. The Bible says otherwise.
There will be both a...
#1. Pre-Tribulation Rapture (Being Changed in the Twinkling of an Eye and Being Caught-Up to Meet the Lord in the Air).
(1 Corinthians 15:51-53) (1 Thessalonians 4:16-18) (Luke 12:40), and a
#2. Mid-Tribulation Gathering Up (by Angels).
(Luke 21:28) (Luke 17:31-37) (Matthew 24:15-22).
For there is a call to the wedding (i.e. the Pre-Trib Rapture):
"And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut." (Matthew 25:10).
There is a call after the wedding to gather more (i.e. The Mid-Trib Gathering):
"And ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately." (Luke 12:36).
An equal point for both of these positions in being true are:
#1. Believers are not appointed unto wrath (1 Thessalonians 1:10) (1 Thessalonians 5:9). The Day of Wrath begins with the breaking of the 6th seal in Revelation 6:17, and the Wrath of God ends in Revelation 15:1. Even the 144,000 (Messianic Jews) are sealed and protected during the Great Tribulation (i.e. the Day (Age) of Wrath). So any believers living during the time of the Midpoint of the Tribulation (before the Day of Wrath) will not be appointed unto Wrath. They will be protected or removed.
The strongest unique points for the Pre-Trib Rapture:
#1. Imminency verses (Matthew 25:13) (Luke 12:40).
#2. The Rapture is a new mystery revealed to Paul (1 Corinthians 15:51).
#3. Paul looked for that blessed hope and appearing of His Lord Jesus Christ and he was not expecting to suffer the Tribulation before seeing His Lord (See Titus 2:13).
#4. In Luke 21:36, we are told to pray so that we may escape all these things. The things in context start at verse 10 with nation rising against nation (See the second seal in Revelation 6:3-4).
Points for the Mid Trib Gathering Up (By Angels):
#1. During the Mid point of the Tribulation (with the Abomination of Desolations), believers are told to look up, for their redemption draws near (See Luke 21:28) (This verse is followed by the 6th seal, which includes Christ being seen sitting on the throne from Heaven, and His coming for the rest of the Elect (i.e. the resistance of believers that were not martyred by the Antichrist by the enforcement of the mark). There are still many trumpet and bowl judgments that needs to take place after the breaking of the 6th seal, and both Daniel and Revelation confirm that there is 3 and a half years left after the antichrist desecrates the Jewish temple.
Midpoint of Tribulation:
(Abomination of Desolations: The antichrist desecrates the Jewish temple).
4th seal = Death (the saints being martyred by the antichrist for their faith in Christ).
5th seal = Saints cry out for vengeance in Heaven for having been martyred by the antichrist.
6th seal = Midpoint Gathering Up: So this is the point when the angels will gather up the remaining surviving elect from the four winds and the uttermost parts of the Earth (See: Mark 13:24-27). This is the gathering up (by angels) of the remaining resistance of believers who were not killed by the Antichrist. Similar to in the Pre-Trib Rapture (that took place prior), Christ comes for His church. For in the Rapture, Paul talks about how Christ will descend from Heaven to meet the church within the air (1 Thessalonians 4:16-17). This "taking up" will most likely happen a second time during the Midpoint of the Tribulation to gather the remaining body of believers.
7th seal.
1st Trumpet Judgement = Official beginning of God’s Wrath, which is an answer to sin the saints cry for vengeance in Heaven with the 5th seal.
#2. For the Elect's sake, the tribulation days will be shortened (Matthew 24:22).
Understanding the End Times is a spiritual thing; So I prefer not to endlessly debate on this topic. If you want to debate it, start another thread. But please know that you would have to offer something substantial biblically in order for me to respond in return with the Bible.
The Bible’s teaching that serious sin is separation from GOD,
"But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear." (Isaiah 59:2).
"Now we know that God hears not sinners: but if any man be a worshipper of God, and does his will, him he hears." (John 9:31).
[God said to Adam,]
"But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die." (Genesis 2:17).
[Eve said to the serpent,]
"But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. (Genesis 3:3).
And the serpent said unto the woman,
"Ye shall not surely die." (Genesis 3:4).
"...she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat. And the eyes of them both were opened, and they knew that they were naked..." (Genesis 3:6-7).
"Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned." (Romans 5:12).
"For the wages of sin is death..." (Romans 6:23).
“...whosoever shall say, Thou fool, shall be in danger of hell fire.”
(Matthew 5:22).
28 “But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
29 And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
30 And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.” (Matthew 5:28-30).
“But whoso committeth adultery with a woman lacketh understanding: he that doeth it destroyeth his own soul.” (Proverbs 6:32).
“But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.” (Matthew 6:15).
“Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.” (Matthew 7:21)
Important Note: If you were to look at 1 Thessalonians 4:3 you would learn that the will of God (i.e. the Father) is to be holy or it is our sanctification; And Hebrews 12:14 says, without holiness no man shall see the Lord.
“22 On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’
23 And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’” (Matthew 7:22-23 ESV).
“26 And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:
27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.”
(Matthew 7:26-27).
“15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
20 Wherefore by their fruits ye shall know them.” (Matthew 7:15-20).
"For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins." (Hebrews 10:26).
"he that commits sin is of the devil." (1 John 3:8).
"everyone who does evil hates the light." (John 3:20).
"Repent therefore of this thy wickedness, and pray God, if perhaps the thought of thine heart may be forgiven thee." (Acts of the Apostles 8:22).
6 "If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth.
7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin." (1 John 1:6-7).
"He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him." (1 John 2:4).
"Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him." (1 John 3:15).
"He that saith he is in the light, and hateth his brother, is in darkness even until now." (1 John 2:9).
"In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother." (1 John 3:10).
41 "The Son of Man will send his angels, and they will gather out of his kingdom all causes of sin and all law-breakers,
42 and throw them into the fiery furnace. In that place there will be weeping and gnashing of teeth.
43 Then the righteous will shine like the sun in the kingdom of their Father. He who has ears, let him hear." (Matthew 13:41-43 ESV).
“For by thy words thou shalt be justified, and by thy words thou shalt be condemned.” (Matthew 12:37).
"They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate." (Titus 1:16).
3 "If any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness;
4 He is proud, knowing nothing,..." (1 Timothy 6:3-4).
"...God resisteth the proud, but giveth grace unto the humble."
(James 4:6).
21 For if God spared not the natural branches, take heed lest he also spare not thee.
22 Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off." (Romans 11:21-22).
16 "There is a sin unto death..."
17 "...and there is a sin not unto death." (1 John 5:16-17).
"But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death." (Revelation 21:8).
19 "Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God." (Galatians 5:19-21).
5 "Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affe
ction, evil concupiscence, and covetousness, which is idolatry:
6 For which things' sake the wrath of God cometh on the children of disobedience:
7 In the which ye also walked some time, when ye lived in them." (Colossians 3:5-7).
5 “...God;
6 ...will render to every man according to his deeds:
7 To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
8 But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,
9 Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;
10 But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:
11 For there is no respect of persons with God.
12 For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law” (Romans 2:5-12).
“But when the righteous turneth away from his righteousness, and committeth iniquity, and doeth according to all the abominations that the wicked man doeth, shall he live? All his righteousness that he hath done shall not be mentioned: in his trespass that he hath trespassed, and in his sin that he hath sinned, in them shall he die.” (Ezekiel 18:24).
9 “Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. “ (1 Corinthians 6:9-10).
“Even so faith, if it hath not works, is dead, being alone.” (James 2:17).
"And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth." (Matthew 25:30).
“For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.” (Romans 8:13).
In the book of Job: The Leviathan was a real fire breathing dragon mentioned alongside other real animals.
As for dragons and the Ark:
If you were to read Job, the Leviathan had the capacity to dwell within the deep part of the sea.
"He maketh the deep to boil like a pot: he maketh the sea like a pot of ointment." (Job 41:31).
But lets say he was a land dwelling creature. If God called the animals onboard the Ark (and he did - see Genesis 6), then God could have surely called the baby dragons onboard the Ark and made them to be tame so as not to attack, just like other predatory animals. Anyways, your lack of belief in dragons as described in the Bible does not undo the reality or truth of them. The Bible is true in what it says on dragons. Your unbelief in them does not undermine Scripture that talks about them as real creatures.
In any event, may the Lord's goodness shine upon you today (even if we disagree).
