"For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit: By which also he went and preached unto the spirits in prison; Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water. The like figure whereunto [even] baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ: Who is gone into heaven, and is on the right hand of God; angels and authorities and powers being made subject unto him." (1 Peter 318-22 KJV)
"For for this cause was the gospel preached also to them that are dead, that they might be judged according to men in the flesh, but live according to God in the spirit." (1 Peter 46 KJV)
This seems to clearly teach word that quickens the spirit to life can come forth and affect those whose flesh has died but yet are existing as spirits in hades. Certainly in the Lazarus and the rich man parabolic story the rich man went though a change of mind and heart to be so concerned for his brothers. (We really need to give more heed to how we can relieve the suffering of others we come into contact with on our path. We have good works preordained for us to do in our assigned path.)
