If anything disproved the rapture it would give cause for many to say that God was the author of confusion, for the rapture is revealed throughout scripture, including in the law, several times, and which Paul certainly alluded to here;
Colossians 2:14-17 KJV
Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; [15] And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it. [16] Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: [17] Which are a shadow of things to come; but the body is of Christ.
The handwriting of ordinances that was against us and which was contrary to us is the law which deals with meat and drink and holy days and new moons and Sabbath days and Paul says the law is prophetic;
Which are a shadow of things to come;
Here is one of the several foreshadowing prophecies of the rapture revealed in the law in chapter eight of Genesis.
The number 8 in scripture represents (amongst other things) “new beginnings” and the prophecy of Christ’s first advent is revealed in the first occurrence of double eight in Genesis, Noah being man’s first new beginning, (Genesis 8.1) and Christ being the second.
Genesis 8:8
[8] Also he sent forth a dove from him, to see if the waters were abated from off the face of the ground; [9] But the dove found no rest for the sole of her foot, and she returned unto him into the ark, for the waters were on the face of the whole earth: then he put forth his hand, and took her, and pulled her in unto him into the ark.
The first sending of the dove (the symbol of the Holy Spirit which revealed Christ) which is sent forth from the ark in
Genesis 8.8, she finds no rest for the sole of her foot. SINGULAR.
The first time Christ is sent forth from the ark of heaven He finds no rest for the sole of ONE foot.
One of the symptoms of a victim of crucifixion was the heel of the lower foot (which stood directly on the nail) would turn black from the extreme bruising. Genesis 3.15.
The second time the dove is sent forth she returns to the ark with an olive leaf in her mouth.
The second time Christ is sent forth from heaven He returns to the ark of heaven with the church (His bride). (1 Thessalonians 4.16) The olive tree in scripture is a symbol of the church.
Only one leaf of the tree is carried back to the ark.
Matthew 7:14 NKJV
Because narrow is the gate and difficult is the way which leads to life, and there are few who find it.
The third time the dove is sent forth from the ark she does not return to Noah.
The third time Christ is sent forth from the ark of heaven he does not return to God but remains and rules on earth for a thousand years.
Isaiah 46:10 KJV
Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:
The rapture is a certainty, revealed in the law many times in many different scriptures. God is not the author of confusion as you believe.
