The question of the after life can come under many definitions of belief, the Egyptians believed in it so much
They truly had a book of the dead, they also buried items in the grave with them including their families and servants.
This is where some believe in it come from.
But again as an example, when Noah was declared a righteous man he did not die in the flood waters , but a vessel was built to save those
Who lived according to God's standards and not tainted from the population on earth at that time.
Again we face another clean up. No people will not be rushed up into a heavenly realm just because they are good, the earth is still good for
Humans and those left here after the clean up
Will make earth a paradise in every sense.
Mentally , physically, economically.
War , hate , crime, greediness will be forgotten.
If people can not learn and be educated here on earth first then why would God allow badness and ignorance in his peaceful realm .
No he will not allow it ,
Remember satan was thrown out of heaven by Jesus Known as Michael.
Re 12:9 So down the great dragon was hurled, the original serpent, the one called Devil and Satan, who is misleading the entire inhabited earth; he was hurled down to the earth, and his angels were hurled down with him.
There are no rebels in Heaven after death a human does not go to a after life. But waits for the resurrection hope to rise on earth again when cleaned and paradise restored,
Joh 5:28 Do not be amazed at this, for the hour is coming in which all those in the memorial tombs will hear his voice
Joh 5:29 and come out, those who did good things to a resurrection of life, and those who practiced vile things to a resurrection of judgment.
So what ever you do in this life as being educated by Jesus will be determine by your answer to accept or decline truth, to inter under his administration.
