Thats a bogus interpretation of Revelation 2 and 3. There is nothing in the Bible to support the theory. Its an example of dispensational allegorizing.
There is nothing in the Bible that gives the meaning of the number 7, but you can determine the meaning. Its an allegory. The fact that there are 7 churches adds significance.
What exactly are we watching for? All I suspect is well see her conversion en mass to faith in Jesus Christ prior to His coming.
I, too, am looking for Israels conversion but not yet. Her blindness will last until the end of the times of the gentiles. Note here that blindness is another allegory. Consider Joseph from the book of Genesis. Joseph is a type of Christ. I know it does not say so in the Bible, but by observation, we can see the events in Genesis predict things that happen to Christ. Some are history some are still prophecy. All are significant.
Now I speculate. I believe we are in the years of plenty right now. There is an abundance of spiritual food
Amos 8:11 Behold, the days come, saith the Lord GOD, that I will send a famine in the land, not a famine of bread, nor a thirst for water, but of hearing the words of the LORD:
Its possible the rapture could be part of what brings on a famine. What do you suppose the Jews are going to find when they go looking for food?
There is nothing in the Bible that gives the meaning of the number 7, but you can determine the meaning. Its an allegory. The fact that there are 7 churches adds significance. There were seven real churches in Asia Minor. This fact alone in no way supports the notion that the churches somehow represent distinct and identifiable dispensations within the so-called church age. That is pure dispensational allegorizing.
What do you suppose the Jews are going to find when they go looking for food?
Nothing, since the church will be gone according to the dispensational theory.
According to the Bible and contra dispensationalism, the Church will be preserved until Christ returns at the Second Coming. It will hold forth the truth of the gospel to all nations until the end.
