veteran,
My question to you is: how can the following prophecy by Joel....
....
...be fulfilled if there is no one (Chrisitian or God fearing Jew which have not taken the "mark-of-the-beast) left in Jerusalem based on your position from Luke 21?
The timeline of that section of Joel 2 is not that difficult to understand...
Joel 2:18-32
18 Then will the LORD be jealous for His land, and pity His people.
What's the context of the Book of Joel been prior to this section of Joel 2:18-32? It's about the locust army being sent upon God's people and their land involving a judgment, their becoming a reproach by being subdued under the power of the heathen. But AT THIS VERSE, that changes!
19 Yea, the LORD will answer and say unto His people, "Behold, I will send you corn, and wine, and oil, and ye shall be satisfied therewith: and I will no more make you a reproach among the heathen:"
No more a reproach upon His people by the heathen. The subject of their being subdued changes. That means the power of Christ's enemies having ended.
20 But I will remove far off from you the northern army, and will drive him into a land barren and desolate, with his face toward the east sea, and his hinder part toward the utmost sea, and his stink shall come up, and his ill savour shall come up, because he hath done great things.
Then God gives a specific time marker. The great army out of the northern quarters is about Gog and his band of Ezekiel 38-39 coming upon the mountains of Israel, and God stepping in to destroy that great army. Israel will be burying the bones of that army for seven months after that event, and the burial place will be called Hamongog. God's destruction upon that army is the supper of the great God mentioned at the end of Rev.19, which also coincides with Christ's second coming on a white horse as written there too. Not difficult at all to understand that's the timing our Heavenly Father is speaking of there in Joel 2:20.
21 Fear not, O land; be glad and rejoice: for the LORD will do great things.
The destruction of that northern army will be a great thing God will do, a miracle even, and it's going to get the attention of all nations and peoples on earth that are left. The purpose for it is to show Who really is The God. That's part of God's Message in the Ezek.39 chapter involving that day of destruction. God is going to claim His people, and the lands He promised Israel's fathers.
22 Be not afraid, ye beasts of the field: for the pastures of the wilderness do spring, for the tree beareth her fruit, the fig tree and the vine do yield their strength.
23 Be glad then, ye children of Zion, and rejoice in the LORD your God: for He hath given you the former rain moderately, and He will cause to come down for you the rain, the former rain, and the latter rain in the first month.
24 And the floors shall be full of wheat, and the fats shall overflow with wine and oil.
Per the Joel context, when will all that happen? AFTER that destruction of the northern army He mentioned in verse 20.
25 And I will restore to you the years that the locust hath eaten, the cankerworm, and the caterpiller, and the palmerworm, My great army which I sent among you.
There it is. God has promised He will RESTORE to them what that locust army devoured. But when, before the northern army's destruction? Of course not, but AFTER He destroys that locust army.
26 And ye shall eat in plenty, and be satisfied, and praise the name of the LORD your God, That hath dealt wondrously with you: and My people shall never be ashamed.
27 And ye shall know that I am in the midst of Israel, and that I am the LORD your God, and none else: and My people shall never be ashamed.
That's about the restoration of Israel, even points to Rev.20 through 22 about God coming to dwell in the midst of His saints, with the new Jerusalem on earth. Those who wait on His coming will never be ashamed, meaning the five wise virgins who do not fall away from Him in the end.
28 And it shall come to pass afterward, that I will pour out My spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:
29 And also upon the servants and upon the handmaids in those days will I pour out My spirit.
30 And I will shew wonders in the heavens and in the earth, blood, and fire, and pillars of smoke.
31 The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD come.
32 And it shall come to pass, that whosoever shall call on the name of the LORD shall be delivered: for in mount Zion and in Jerusalem shall be deliverance, as the LORD hath said, and in the remnant whom the LORD shall call.
(KJV)
When Apostle Peter quoted the above 28-32 verse on Pentecost in Acts 2, he said "But this is that which was spoken by the prophet Joel". Pentecost was only an 'example' of this prophecy from Joel about God pouring out of His Spirit upon the remnant whom He would call. It does NOT mean the Joel prophecy was fulfilled on Pentecost day in Acts 2, simply because those Joel verses include the topic of signs leading up to the day of the LORD, i.e., the time of Christ's second coming. The Pentecost event was 1st century A.D. timing, and here we still are today awaiting Christ's second coming and the restoration of all things under Him.
In Luke 21, Christ is warning His servants (Christians) in Judea to get out of that area when they see those armies surrounding Jerusalem. Per Josephus, many of the Christians there actually did flee Judea when they saw the Roman armies surrounding Jerusalem in 70 A.D., and that serves as a blueprint for the future final fulfillment of that which is yet to come with the final Antichirst.
You simply are failing to rightly divide the timeline of that Joel Scripture.
