"These last days" was a then present reality for the writer of Acts, was it not? He is clearly testifying that the last days were underway during Christs earthly ministry.
No that doesn't work. It says the last days shall come! Or..there shall (future) come in the last days.....
And how about this, you think this was fulfilled in Jesus' day?
Mic 4:1 - But in the last days it shall come to pass, that the mountain of the house of the LORD shall be established in the top of the mountains, and it shall be exalted above the hills; and people shall flow unto it.
Isa 2:2 And it shall come to pass in the last days, that the mountain of the LORD'S house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.
3 And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem.
4 And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more.
5 O house of Jacob, come ye, and let us walk in the light of the LORD.
Plenty of perilous times and folks walking after their own lusts In the "These last days" of the Temple era leading up to its desolation.
I don't see the elements burning with fervent heat and the heavens pass??
2 Peter 3:
3 Knowing this first, that there shall come in the last days scoffers, walking after their own lusts,
4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.
5 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:
6 Whereby the world that then was, being overflowed with water, perished:
7 But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
That is precisely what I am saying.
Though They may claim it, the fact is Today's Jews don't follow the mandatory feasts of Moses and haven't for 2000 years. Why don't they do what Moses commanded? Because today's "jews" don't follow the Old Covenant whatsoever. Just read Leviticus and ask yourself, "Do any Jews today do this"?
I can assure you no human being alive today can even do 50% of what the law requires, and what they did prior to AD70.
I think I can assure you the Pharisees didn't either!
