Jesus confirms in John 5:
24- 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. (Because they are already dead, is only a matter of time)
25- 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.
(The living dead, who listen, will resuscitate).
28- Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice,:
29- 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.
Christ already prophetized Daniel 12:
2- And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame [and] everlasting contempt.

(Many, not all), But Who listened, will resuscitate; fair or unfair, they are committed with heaven or hell, whoever died as a child, or those that never heard, won´t resuscitate, to be judged as Paul speaks in Romans 2:
12- For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;
In hell, the punishment will be different between the servant who received a lot, and the one that received a little. Jesus speaks well about that in Luke. 12:
47- And that servant, which knew his lord's will, and prepared not [himself], neither did according to his will, shall be beaten with many [stripes].
48- But he that knew not, and did commit things worthy of stripes, shall be beaten with few [stripes]. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more.
