You would be hard pressed to find ANY Bible commentary on either Daniel's end time prophesy or the book of Revelation. They were a closed book that none understood.
Jesus taught that the Holy Spirit would come and indwell believers for three purposes. Sealing our salvation as the earnest, producing good works as fruit of His presence, and enlightenment to understand the Word of God. The last purpose is found in
John 16:12-13 "I have yet many things to say unto you, but ye cannot bear them now.
13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
The takeaway here is that some things are not bearable for us to understand, and some things are not revealed to everyone or until the Spirit chooses to disclose them.
I Corinthians 2:14-16 "But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
15 But he that is spiritual judgeth all things, yet he himself is judged of no man.
16 For who hath known the mind of the Lord, that he may instruct him? but we have the mind of Christ."
Anything we believers understand of the Word of God is due to the Holy Spirit giving us illumination. If God has for some reason reserved certain understanding for a future time, illumination for that is withheld. Such is exactly the case for Daniel's end time prophesy, and he records his instructions for us in Daniel chapter 12. Vs4 - "But thou, O Daniel, shut up the words, and seal the book, even to the time of the end:" Vs9 - "And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end."
It can hardly be said that the Bible does not contain the teaching of the catching away of saints, but it is evident that theologians have not understood this teaching until recent. The outpouring of commentary, correlation between Daniel's prophesy and Revelation, and our world quickly descending into likeness of end time descriptions, is nothing short of amazing. I believe we can all agree, the end times are very near. The unsealing of these things in this day, is telling.
