Where does the Bible says there is a Rapture before the Great Tribulation?
The Bible always speak of an Ingathering during the Second Coming, but never of a rapture before the Great Tribulation. Is called "rapture" that which is alleged to occur before the Great Tribulation. Is called "ingathering" that which will occur at the moment of the Second Coming of Jesus Christ.
I can point to various verses that deal with the return of the Lord, in which the existence of the Ingathering is clearly announced during the Second Coming of our Lord Jesus Christ. But I have not seen a single one where there is any clear mention of a sudden, silent and secret Rapture before the Great Tribulation.
Matthew, Mark and Luke included the Prophetic Sermon in their Gospels. In that sermon Jesus speaks of the events that would occur from the moment he was speaking, until his Second Coming. In spite that the Lord was speaking to his Church, in the form of his apostles, at no instance he tells them that there is going to be a rapture before the Great Tribulation. Nevertheless, He does speak clearly and specifically of the occurrence of an Ingathering after the Great Tribulation and during his Second Coming.
How can we believe in a rapture which Jesus never mentioned and which is not mentioned in any Scripture? Moreover, how can we think that if Jesus has spoken of the events that would occur until his Second Coming, He would forget to mention the Rapture or warn about it? Or how can we think that he would leave the leaders of his Church ignorant about an issue so transcendentally important? The answer is quite simple: the Rapture before the Great Tribulation simply does not exist, it is a diabolical ruse to deceive the Christians, as Jesus himself warned, as well as the apostle Paul. But, unfortunately, most of Christians have allowed themselves to be deceived.
If the Rapture were real, the Lord, would have spoken about it during the Prophetic Sermon, just as He did about the Ingathering occurring after the Great Tribulation. Review for yourselves, verse by verse, each chapter in each of the three gospels where the Prophetic Sermon is presented (Mt, Mr y Lk), you will see that nowhere our Lord Jesus Christ warns his Church that there would be a Rapture previous to the Great Tribulation.
After concluding our own investigation into this matter, would we continue believing this heresy? Brethren, it is justifiable that a Christian be deceived, but it is unjustifiable that he would insist in remaining deceived, without having any reasons that would support those beliefs, and without being able to answer against the reasons that here are presented.
God gave the Bible so that all may understand it, not only the learned. The prophecies and doctrines in the Bible are clear; anyone can understand them without having to have studied theology, Greek, Hebrew, hermeneutics, etc., nor having to graduate from a seminary. God does not give His revelations so that only a few experts like Caiaphas and Gamaliel can understand them. He gives them so that fishermen like John, Peter and James may have access to the truth, if indeed they desire to know the truth.
The Lord Jesus said once that God had revealed these things to the little and not to the learned and expert. Hence, we don't necessarily need to be learned or experts to understand.
“At that time Jesus answered and said, I thank thee, O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.” (Mt 11:25)
