All enter heaven through Jesus, He provided that path to the Father by dying on the cross.
But not all have known Jesus or the Father here on Earth. Doesn't matter though, they will know them soon enough if the Lord decides that meeting is warranted.
Agreed that the Lord may do anything He chooses to do, but is there a scriptural basis for believing that He makes exceptions after death?
Another question is what happened to the millions who lived before the Gospels were preached. Did everybody go to Hell?
