The Lord God Almighty has determined that those who are late to the kingdom of God shall not inherit eternal life, unless they were incapacitated and/or incapable of making informed decisions about their future, and made said decisions as soon as they were capable of doing so. At the conclusion of Christ's millennial reign, they will need to face the final judgment along with those who had only the indwelling Holy Spirit, but were never sealed or raptured.
The Lord will note that they had prayed to be sealed and raptured, but were late in doing so. They will have an advantage over those who had never sought to be sealed or raptured, and will be identifiable by virtue of the fact that the circle of light around their head is not joined at the top. At any point during the thousand years of Christ's millennial reign, the Lord may decide to remove the stigma and complete the seal by joining the circle.
The Lord God Almighty El Shaddai.
