You frame your entire doctrine on a phrase "day of the lord"
Then pretend the pretrib rapture verses are somehow missing.
Oh my, you really dont know what the "Day of the Lord" is? Thats when Christ returns to this earth, destroys the wicked and sets up His kingdom. I thought everyone knew that. Heres some scriptures proving the "Day of the Lord" is after the tribulation period.
MARK 13 [19] For in those days shall be affliction, such as was not from the beginning of the creation which God created unto this time, neither shall be.[20] And except that the Lord had shortened those days, no flesh should be saved: but for the elect's sake, whom he hath chosen, he hath shortened the days.[21] And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not:[22] For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect.[23] But take ye heed: behold, I have foretold you all things.
{verses 19-23 describe the trib period}
{verses 24-27 describe the Day of the Lord}
[24] But in those days,
AFTER THAT TRIBULATION, the SUN SHALL BE DARKENED, AND THE MOON SHALL NOT GIVE HER LIGHT,[25] And the stars of heaven shall fall, and the powers that are in heaven shall be shaken.[26] And then shall they see the Son of man coming in the clouds with great power and glory.[27] And then shall he send his angels, and shall
GATHER TOGETHER HIS ELECT from the four winds, from the uttermost part of the earth to the uttermost part of heaven.
In Mark you see the great tribulation period is FOLLOWED by a dark sun and dark moon and the gathering of Gods people {in the twinkling of an eye}
JOEL 2 [10] The earth shall quake before them; the heavens shall tremble:
THE SUN AND THE MOON SHALL BE DARK, and the stars shall withdraw their shining: [11] And the LORD shall utter his voice before his army: for his camp is very great: for he is strong that executeth his word: for
THE DAY OF THE LORD is great and very terrible; and who can abide it?
JOEL 2 [30] And I will shew wonders in the heavens and in the earth, blood, and fire, and pillars of smoke. [31]
THE SUN SHALL BE TURNED INTO DARKNESS, AND THE MOON INTO BLOOD, BEFORE THE GREAT AND THE TERRIBLE DAY OF THE LORD COME.
In Joel we find the sun will be darkened and the moon into blood BEFORE the Day of the Lord
ACTS 2[19] And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke: [20] The sun shall be turned into darkness, and the moon into blood, BEFORE THAT GREAT AND NOTABLE
DAY OF THE LORD COME:
