Only intelligent people who have made their bible their friend will understand this and know the truth and be free from the grip of religion. You will recall that the disciples of Jesus asked him a similar question in Luke 13:23(take note : this question was asked before Jesus was crucified) But i think this is a wrong question to ask in this dispensation after Christ has been crucified and he is resurrected. Rather, the right question that should be asked in today's reality is "Are there few that are in heaven? " seeing that heaven is already here with us through the death and resurrection of Christ, unlike the period when Christ has not been crucified. we have to consider time when reading the bible. there was time before the crucifixion of Christ which include the period when Jesus was yet alive on earth with his disciples before he was crucified, and there is was time after his death and resurrection, this is where we Christians belong which is heaven. what am i driving at? we this current era Christians without considering time, read bible that was written approximately 2000 years ago and try to make what we have read our current day reality and our future,it doesn't work that way. For our benefits, the bible should be treated today as a book and past events and nothing else. Are there few that are in heaven? The answer is no! Currently, there are billions of believers worldwide saved by Grace, they are not few.
