Forgiveness After Death?

In which He went and preached to the spirits in prison, [The souls of those] who long before in the days of Noah had been disobedient, when God's patience waited during the building of the ark in which a few [people], actually eight in number, were saved through water. 1 Peter 3:19-20

There is a very dominate belief among Christians and it is that once we die all chance for forgiveness is over. If that were true, why did Jesus go to Hades to preach to people? If it was the Truth that once we die there is no chance to be forgiven then Jesus wasted His time and He was very cruel. Think of it, these people are in Hades, there is no chance to be forgiven, and Jesus goes down there is preaches to them about salvation and there is absolutely no chance that they can have it.

The glorious Truth however is that our Father is not a respecter of persons, Acts 10:34. So if Jesus went to the lost and gave them another chance, He will do it again. Why do you think that our Father will raise the dead up and reunite them with their bodies after the Millennial Reign of Christ, Revelation 20? He does this so that they will have another opportunity to be forgiven and allowed to live. They will not be the Bride, but they will be the guests of the Bride. Everyone who has not committed Blasphemy of the Holy Spirit will be forgiven and allowed to stay. They will have paid the price for their transgressions in Hades. They will have reaped what they have sown and then they will be forgiven by us and allowed to stay in the Kingdom of Heaven.

Truly and solemnly I say to you, all sins will be forgiven the sons of men, and whatever abusive and blasphemous things they utter; But whoever speaks abusively against or maliciously misrepresents the Holy Spirit can never get forgiveness, but is guilty of and is in the grasp of [a]an everlasting trespass. Mark 3:28-29
