OK, again. The verses 2: 23- 27 describe the situation and the circumstances of the nation of Israel.
✝ Joel 2:23
"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."
✝ Joel 2:24
"And the floors shall be full of wheat, and the fats shall overflow with wine and oil."
✝ Joel 2:25
"And I will restore to you the years that the locust hath eaten, the cankerworm, and the caterpillar, and the palmerworm, my great army which I sent among you."
✝ Joel 2:26
"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.
✝ Joel 2:27
"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."
When this happend, then follow what we read in the Verses 2:28-31
✝ Joel 2:28
"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: "
✝ Joel 2:29
"And also upon the servants and upon the handmaids in those days will I pour out my spirit."
✝ Joel 2:30
"And I will show wonders in the heavens and in the earth, blood, and fire, and pillars of smoke."
✝ Joel 2:31
"The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD.
So according the text, Israel had this situation not expierienced till today.
So, is vers 2,28 not fully fullfilled!!
If you claim different then you have to take the vers out of the context!!
And please consider that the Adressat of this text is the nation of Israel and not the whole world.
