It's the spotless Blood of The Lamb that saves. Jesus shed that for all on the cross. one cannot proclaim Jesus is Lord after death - because that is where one gets it's just rewards. We decide our own fate by our choices here and now. Besides, if they didn't want to serve and praise Our Savior here, why would they want to be with Him for all eternity!
Don't be misled, as you can see there are many false doctrines out there to deceive. Stay the course.
I cannot imagine anyone wanting to spend one millisecond in hell...Christ was all about forgiveness, yea, even for the stupid. Only one sin is mentioned unforgivable: blasphemy of the Holy Spirit (denial of God existence, or atheism)
