I take it that "the last time" (1 Pe 1:5) and "these last days" (Heb 1:2) are different but related meanings. These last days as I understand it is the church age, which is not something that goes on forever. But at this I imagine you are ready to challenge me with your favorite verse..
haha
The way I reconcile this is there will be a new age in consummation and it won't be the church age anymore, but you'll still have a church. Maybe the church, or the bride, will comprise all the old and New Testament saints on earth. Granted, I could be misunderstanding this verse.
Generally speaking, first century Jews had the conception of two ages—the Mosaic Age and the Messianic Age— also called the Old Covenant and New Covenant. (Jer. 31:31f). Because the New Testament writers lived before the definitive end of the Mosaic Covenant in AD 70, they describe the two ages as “this age” (Mosaic) and “the age to come” (Messianic, Christian, Kingdom of God). After the destruction of the Jewish state in AD 70, believers gained the fullness of the Kingdom of God. The latter is the New Heaven and New Earth.
For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind. There shall be no more thence an infant of days, nor an old man that hath not filled his days: for [the child shall die] an hundred years old; but [the sinner being an hundred years old shall be accursed].
Isaiah 65:17,20
For as the new heavens and the new earth, which I will make, shall remain before me, saith the Lord, [so shall your seed and your name remain.]
Isaiah 66:22
And I heard a voice from heaven saying unto me, Write, [Blessed are the dead which die in the Lord from henceforth:] Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
Revelation 14:13
_____
In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old [is ready to vanish away].
Hebrews 8:13
The Holy Ghost this signifying, [that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing]:
Hebrews 9:8
[And the temple was filled with smoke from the glory of God, and from his power; and no man was able to enter into the temple,] ***till the seven plagues of the seven angels were fulfilled.
Revelation 15:8,16:17f (Leviticus 26:18,21,24,28)
so Christ was offered once to bear the sins of many. To those who eagerly wait for Him [He will appear a second time,] apart from sin, [for salvation].
Hebrews 9:28
For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. [And the dead in Christ will rise first].
1 Thessalonians 4:16
[And many of those who sleep in the dust of the earth shall awake, Some to everlasting life, Some to shame and everlasting contempt.]
“How long shall the [fulfillment of these wonders] be?”
***when the power of the holy people has been completely shattered, all these things shall be finished.
“My lord, what shall be [the end of these things?”]
“Go your way, Daniel, for the words are closed up and sealed till the [time of the end].
“But you, go your way till the end; for you shall rest, and [will arise to your inheritance at the end of the days].”
Daniel 12:6-9,13
Then he said to me, “These words are faithful and true.” And the Lord God of the holy prophets sent His angel to show His servants [the things which must shortly take place.]
[“Behold, I am coming quickly!] Blessed is he who keeps the words of the prophecy of this book.”
And he said to me, “Do not seal the words of the prophecy of this book, [for the time is at hand.]
[“And behold, I am coming quickly,] and My reward is with Me, to give to every one according to his work.
He who testifies to these things says, [“Surely I am coming quickly.”]
Revelation 22:6-7,10,12,20
***Then let those who are in Judea flee to the mountains, let those who are in the midst of her depart, and let not those who are in the country enter her. [For these are the days of vengeance, that all things which are written may be fulfilled.] But woe to those who are pregnant and to those who are nursing babies in those days! For there will be great distress in the land and wrath upon this people.
Luke 21:21-23
***“Woe to you, scribes and Pharisees, hypocrites! Because you build the tombs of the prophets and adorn the monuments of the righteous, 30 and say, ‘If we had lived in the days of our fathers, we would not have been partakers with them in the blood of the prophets.’ “Therefore you are witnesses against yourselves that you are sons of those who murdered the prophets. [Fill up, then, the measure of your fathers’ guilt.] Serpents, brood of vipers! How can you escape the condemnation of hell? Therefore, indeed, I send you prophets, wise men, and scribes: some of them you will kill and crucify, and some of them you will scourge in your synagogues and persecute from city to city,
[that on you may come all the righteous blood shed on the earth, from the blood of righteous Abel to the blood of Zechariah, son of Berechiah, whom you murdered between the temple and the altar. Assuredly, I say to you, all these things will come upon this generation.] “O Jerusalem, Jerusalem, the one who kills the prophets and stones those who are sent to her! How often I wanted to gather your children together, as a hen gathers her chicks under her wings, but you were not willing! See! Your house is left to you desolate;
