Jesus in John chapter 5 suggest that those who believe in the one who sent Him and hears Him words WILL (present tense) have everlasting life and shall pass from death unto life..
After this He says that the time is soon approaching (foreshadowing His burial) that ALL who are in the grave (buried) shall hear His Voice and those who have done good shall resurrect unto everlasting life while those who have done evil shall resurrect unto damnation..
Jesus is saying that the living (literally those alive then and those alive now) who hear and believes will be saved, but the dead will soon hear His voice [ALL the dead will hear His voice when he descends into the grave] and shall come forth either in everlasting life or damnation according to their works they have done while alive..
At least that's how I read it.. so much is revealed in these few passages, but what Jesus is telling his accusers is that he has the authority to judge all because he is both the Son of God and the Son of man and All shall hear his voice and stand before him after death..
So did he preach to the dead in Hades? Or Judge the wicked and deliver good news to the righteous?
"Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life. Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live. For as the Father hath life in himself; so hath he given to the Son to have life in himself; And hath given him authority to execute judgment also, because he is the Son of man. Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation" John 5:24-29
Notice he leaves out the Day of Judgment, but I believe that after death there is no linier time but simply THE judgment, for those who are alive to see this "great and terrible" day and who have believed will not see death but those who remain unbelieving upon His return shall face the 2nd death, the resurrection unto eternal damnation in the lake of fire..
