Correct, but the question is about people during the millennium (if that happens) who are born during that time. However, Christians today still need to repent when we realize we sin.
I see no appreciable difference between that reality now and the millennium.
Also correct, but not in context of the OP. Romans clearly tells us that the law was introduced to increase the awareness of sin.
Rom 5:13 (For until the law sin was in the world: but sin is not imputed when there is no law.
Rom 5:14 Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come.
Sin existed before Moses codified the law, but with no imputation of sin, hardness of heart blinded men to their sins.
Agreed... sort of...
Before the Law, all were condemned to death whether they sinned or not, as Adam's initial sin was imputed to all regardless of any ones individual behavior.
The Law was given to add strength to individual sins, and to add the power to condemn the individual for his or her individual transgressions.
Then Came the Christ who fulfilled the law, made it Obsolete, and It vanished. (Hebrews 8:13)
Now, and forevermore, Human beings are either "in Adam", Just as before the law was given to Moses, and Condemned to Death whether they sin or not, or they are "in Christ" saved even though they are sinners.
Individual Sins are no longer the measuring Stick God uses to determine ones salvation status, in fact, ONLY sinners Get saved.
Christ and the Church in glory will not look like mortal humanity.
Will they/we look like Moses and Elijah did on the mount at the transfiguration when they appeared in their glorified Bodies??
The disciples saw them in their glory, even recognized exactly who they were, yet that vision in no way prevented them form understanding that they (disciples) were still sinful mortals in need of a savior, so your cause/effect scenario doesn't seem to hold up to the scriptural evidence.
So those mortals born in the millennium will need to be taught both what sin is and the need for death for atonement. Satan's release will be the test to see who understood and who did not.
Where is the evidence that Christ's once for all sacrifice on the cross, at that point, becomes null and void, indeed becomes wholly ineffectual for the redemption of those mortals, and instead the resurrection of an obsolete, vanished, less effective covenant where the blood of Bulls and goats is shed to atone for sins, must be set back up?
