Jesus didn't speak to highly of unbelievers and there reward. Read Luke 12:46. Also take a gander at Rev 21:8
"But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolators and all liars will have there part in the lake that burns with fire and brimstone, which is the 2nd death."
Pray for your children.
