However, there is not much hope of your understanding it all unless you are willing to read - without bias -the entire Torah, Prophets and the B'rit Chadasha (renewed convenant).
In Isaiah 53, a portion of scripture that is rarely if ever read in synagogue, the prophet speaks of the suffering servant (Yeshua - which translated means 'and he will save his people from their sin').
If you will read and consider who this servant might be, comparing both Jewish writings AND respected Christian commentaries, you will be hard pressed to come to any conclusion other than that Yeshua is the Messiah. No other explanation is borne out by Scripture, and the Rabinnic explanations generally obfuscate the issue and generally contradict themselves in the process.
Regarding the Rapture (harpatzo in the Greek, meaning to "catch away") it is prophesied to occur "when the fullness of the gentiles be come in".
The nation of Israel was to be "a light to the Gentiles", but they failed. The church is supposed to bless Israel and pray for the peace of Jerusalem, and they also failed. The church is trending that way now, but many still follow a "replacement theology" wherein the term "Israel" is spiritualized and the church has redefined itself as "spiritual Israel" - even though Romans 9,10 & 11 make it unmistakably clear that G-d will never forsake his people. The book of Daniel, most notably Chapters 9 and 12, Daniel is given visions from G-d, through His messenger Michael, of the unfolding history up to and including the "end-times". And in Chap. 12, Verse 1, Michael says "and there shall be a time of trouble, such as never was since there was a naiton even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.Which book would that be? The Lamb's Book of Life - written in Yeshua's blood that was shed for the whole world, as well as for His people Israel, most of whome, heartbreakingly, rejected His messiaship.
The "time of trouble" is the "time of Jacob's trouble - a time the church refers to as the great tribulation. It is at the end of that time that the plan of redemption will come to its fulfilment in Yeshua's return to claim of his people - those who have accepted his identity as Redeemer and L-d of L-ds, the one who reconciles the world to the G-dhead. At that time there will be neither Jew nor Gentile, but rather only each individual's belief in Him, and in His purpose for being born, crucified and resurrected.
If you will examine ALL of the evidence, you will be able to come to your own conclusion. Hope this helps.
A non-sequitur. As anyone with knowledge of the origin of the haftarah reading understands.
