You don’t get very far into reading the Bible and the world is so wicked that God judges and wipes out all but Noah and his family with a flood. This was the time before rainfall, and their was a moisture layer in the atmosphere that protected humanity from UV and cosmic rays giving them much longer lifespans, measured in hundreds of years. So in Isaiah 65 there is perhaps a clue to lifespans that correlates to the waywardness of humanity, as God is giving details of the Millennial Kingdom when Christ rules the world in righteousness with true justice.
Isaiah 65:20
[20] No more shall there be in it an infant who lives but a few days, or an old man who does not fill out his days, for the young man shall die a hundred years old, and the sinner a hundred years old shall be accursed. (ESV)
So after the tribulation period the configuration of the earth will be changed to something similar to what existed before the flood, where long life will extend into hundreds of years, and God seems to indicate an unrepentant sinner will be cut off at 100 years. An interesting time limit given our lifespans in this age. Was this the only way to limit sinful humanity?
And beyond the length of days, there are fundamental changes to the animal kingdom.
Isaiah 65:25
[25] The wolf and the lamb shall graze together; the lion shall eat straw like the ox, and dust shall be the serpent’s food. They shall not hurt or destroy in all my holy mountain,” says the LORD. (ESV)
And God drops in what happens after the Millennial Kingdom. And of interest, this was written hundreds of years before Christ came to His people, or appeared to John to give us the book of Revelation. Consequently, there will be the golden city of Jerusalem which all of God’s children will inhabit with Him for eternity, the size of which is magnificent, and built by God descending out of heaven.
Isaiah 65:17–18
[17] “For behold, I create new heavens and a new earth, and the former things shall not be remembered or come into mind. [18] But be glad and rejoice forever in that which I create; for behold, I create Jerusalem to be a joy, and her people to be a gladness. (ESV)
Maranatha!
Isaiah 65
Judgment and Salvation
[1] I was ready to be sought by those who did not ask for me;
I was ready to be found by those who did not seek me.
I said, “Here I am, here I am,”
to a nation that was not called by my name.
[2] I spread out my hands all the day
to a rebellious people,
who walk in a way that is not good,
following their own devices;
[3] a people who provoke me
to my face continually,
sacrificing in gardens
and making offerings on bricks;
[4] who sit in tombs,
and spend the night in secret places;
who eat pig’s flesh,
and broth of tainted meat is in their vessels;
[5] who say, “Keep to yourself,
do not come near me, for I am too holy for you.”
These are a smoke in my nostrils,
a fire that burns all the day.
[6] Behold, it is written before me:
“I will not keep silent, but I will repay;
I will indeed repay into their lap
[7] both your iniquities and your fathers’ iniquities together,
says the LORD;
because they made offerings on the mountains
and insulted me on the hills,
I will measure into their lap
payment for their former deeds.”
[8] Thus says the LORD:
“As the new wine is found in the cluster,
and they say, ‘Do not destroy it,
for there is a blessing in it,’
so I will do for my servants’ sake,
and not destroy them all.
[9] I will bring forth offspring from Jacob,
and from Judah possessors of my mountains;
my chosen shall possess it,
and my servants shall dwell there.
[10] Sharon shall become a pasture for flocks,
and the Valley of Achor a place for herds to lie down,
for my people who have sought me.
[11] But you who forsake the LORD,
who forget my holy mountain,
who set a table for Fortune
and fill cups of mixed wine for Destiny,
[12] I will destine you to the sword,
and all of you shall bow down to the slaughter,
because, when I called, you did not answer;
when I spoke, you did not listen,
but you did what was evil in my eyes
and chose what I did not delight in.”
[13] Therefore thus says the Lord GOD:
“Behold, my servants shall eat,
but you shall be hungry;
behold, my servants shall drink,
but you shall be thirsty;
behold, my servants shall rejoice,
but you shall be put to shame;
[14] behold, my servants shall sing for gladness of heart,
but you shall cry out for pain of heart
and shall wail for breaking of spirit.
[15] You shall leave your name to my chosen for a curse,
and the Lord GOD will put you to death,
but his servants he will call by another name,
[16] so that he who blesses himself in the land
shall bless himself by the God of truth,
and he who takes an oath in the land
shall swear by the God of truth;
because the former troubles are forgotten
and are hidden from my eyes.
New Heavens and a New Earth
[17] “For behold, I create new heavens
and a new earth,
and the former things shall not be remembered
or come into mind.
[18] But be glad and rejoice forever
in that which I create;
for behold, I create Jerusalem to be a joy,
and her people to be a gladness.
[19] I will rejoice in Jerusalem
and be glad in my people;
no more shall be heard in it the sound of weeping
and the cry of distress.
[20] No more shall there be in it
an infant who lives but a few days,
or an old man who does not fill out his days,
for the young man shall die a hundred years old,
and the sinner a hundred years old shall be accursed.
[21] They shall build houses and inhabit them;
they shall plant vineyards and eat their fruit.
[22] They shall not build and another inhabit;
they shall not plant and another eat;
for like the days of a tree shall the days of my people be,
and my chosen shall long enjoy the work of their hands.
[23] They shall not labor in vain
or bear children for calamity,
for they shall be the offspring of the blessed of the LORD,
and their descendants with them.
[24] Before they call I will answer;
while they are yet speaking I will hear.
[25] The wolf and the lamb shall graze together;
the lion shall eat straw like the ox,
and dust shall be the serpent’s food.
They shall not hurt or destroy
in all my holy mountain,”
says the LORD. (ESV)
