The reconciliation (the true meaning of atonement) and throughout the OT that was that part of redemption that was missing and why "most ... were laid low." Not that God was reconciled to man (for that can not be) but that man must be reconciled to God.
That the "most" were not reconciled to God is why they were "laid low."
The question then is, "Why were they not reconciled?" Because they loved darkness rather than light. The attempted to hide from the light for fear the light would expose their evil.
"HE came to HIS OWN and
HIS OWN receive Him not" John 1.
And as you point out in John 3 some accept Gospel of Christ and the way of escape and some reject it "because they loved darkness rather than light for their deeds were evil".
The message of the saved to the lost is -- "we beg you on behalf of Christ be reconciled to God".
2Cor 5
18 Now all these things are from
God, who reconciled us to Himself through Christ and gave us the ministry of reconciliation,
19 namely, that
God was in Christ reconciling the WORLD to Himself, not counting their trespasses against them, and He has committed
to us the word of reconciliation.
20 Therefore, we
are ambassadors for Christ, as though God were making an appeal through us; we beg you on behalf of Christ, be reconciled to God.
The reconciliation that is going on now via the work of Christ as High Priest is not only in purifying the saints (1John 3:3-5 - Hebrews 9:11-14, Malachi 3:1-6
Malachi 3
1 ""Behold, I am going to send My messenger, and he will clear the way before Me. And
the Lord, whom you seek, will suddenly come to His temple; and the messenger of the covenant, in whom you delight, behold, He is coming,'' says the LORD of hosts.
2 ""But who can endure the day of His coming? And who can stand when He appears? For He
is like a refiner's fire and like fullers' soap.
3 ""He will sit as a smelter and
purifier of silver, and He will
purify the sons of Levi and
refine them like gold and silver, so that they may
present to the LORD offerings in righteousness.
4 ""Then the offering of Judah and Jerusalem will be pleasing to the LORD as in the days of old and as in former years.
5 ""Then
I will draw near to you for judgment; and I will be a swift witness against the sorcerers and against the adulterers and against those who swear falsely, and against those who oppress the wage earner in his wages, the widow and the orphan, and those who turn aside the alien and do not fear Me,'' says the LORD of hosts.
6 ""
For I, the LORD, do not change; therefore you, O sons of Jacob, are not consumed.
What is more - it is well known even among the Jews today that the Lev 16 Day of Atonement at the end of the year - is a day of judgment of the entire world.
So part of the "reconciliation" that is being performed after the cross pertains to the benefit of that judgment when as Dan 7:22 states "
Judgment is passed in favor of the saints" as a result of the "
books that were opened" for the myriads and myriads to see and the "
court that sat" with the Ancient of Days presiding.
in Christ,
