Infants and the Millenium - a Pre-Millenial Quadralemma (Guest Post by Ben. W)

The following guest post by Ben W. presents a question to our premillennial brothers and sisters:
*** Guest Post ***
What happens to babies born during the millennial reign after the return of Christ?

1. Babies are born and some believe in Christ and are saved, others do not and are damned.
2. 2. Babies are born but none of them believe in Christ and they are not saved.
3. 3. Babies are born and all of them believe in Christ and are saved.
4. 4. No babies are born during the millennial reign.

Each of these options is problematic.
1. Babies are born and some believe in Christ and are saved, others do not and are damned.
The problem with this view is that scripture makes it clear that Christ will not return until all of his people have been brought in.
In 2nd Peter 3, Peter makes the argument that Christ has not returned yet, and that God has not yet judged the Earth because not all of God’s people have been saved, “not wishing that any should perish, but that all should reach repentance” God waits until the full number of his people have been gathered.
In Matthew 24:29-31 Jesus says of his own return that he will gather his elect from the entire Earth, “the four winds” North, East, South, West and from one end of Heaven to the other, both those on Earth and those in Heaven will be gathered together upon Christ’s return. All of God’s people will be gathered upon Christ’s return.
Finally, in Romans 11:25 scripture says that “a partial hardening has come upon Israel until the fullness of the Gentiles has come in.” This hardening will end when Christ is reigning from Jerusalem and the temple has been rebuilt. If the hardening of Israel has ended this must mean that the fullness of the Gentiles has come in, and if that’s the case, it would appear that no Gentiles will be saved during the millennial reign.
2. Babies are born but none of them believe in Christ and they are not saved.
This view has the benefit of avoiding the problems brought forth by the previous view; however, it introduces two problems of its own.
First, it describes a world in which Christ is physically ruling from the Earth, and yet, there are none for a thousand years, while Satan is bound from deceiving the nations, that believe in him.
Even from the view of premillennialism the outlook is never this bleak, which leads to the second problem.
In Isaiah 65:23-24, which premillennialists view as a description of the millennial kingdom, it says:

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.
Before they call I will answer;
while they are yet speaking I will hear.

Here we see it is said that the children born during the millennial reign, and their children will be called offspring of the blessed of the Lord. If every generation’s descendants are called the offspring of the blessed of the Lord, it follows that their parents too will be his blessed. The next verse makes it clear that God will hear and answer the prayers of these generations; surely this is not descriptive of a planetary population that has rejected King Jesus and his rule.
In Zechariah 14, and Micah 4 it is said that all the nations will come and worship Christ in Jerusalem when he reigns there.
If we read these texts without spiritualizing or allegorizing it seems clear that there will be a partial, if not total conversion to Christianity by the population of the Earth during this time.
3. Babies are born and all of them believe in Christ and are saved.
If there are no unbelievers during the millennial reign, who rebels against Christ at the end of the 1000 years? If all those born during the millennium are saved, there is no one to rebel as described in Revelation 20:7-10.
4. No babies are born during the millennial reign.
This position too fails because as we previously saw, Isaiah 65 describes the offspring of those living during the millennial reign, and as we noted in the previous option, if there are no unbelievers in the millennium, then there is no one to rebel against Christ when Satan is loosed.
A person might argue that, while there are no babies born during the millennial reign, those unbelievers still alive when Christ returns will enter into it, and they will be the ones to rebel. However, Revelation 19:17-21 describes the total destruction of all unbelievers upon Christ’s return. There will be none of God’s enemies left after Christ returns.

As noted elsewhere, I (TurretinFan) am not particularly dogmatic on eschatology. I found this puzzle interesting, but it's not the reason I'm postmillenial. I'm postmillenial because I think the Lord is coming back on the last day, as per John 6 and 1 Corinthians 15. I think the author of the post, Ben. W., is actually ameillenial, which is a quite similar position.
