Any suggestions on this would be great?

-your in a circular room with 2 identical doors and 2 identical sentries guarding each door, one door leads to heaven and the other door leads to hell. The sentry guarding the door to heaven will always tell the truth whereas the sentry guarding the door to hell will always tell lies! you can only ask one question to one of the sentries to find out where the doors lead but cant ask outright if their door leads to heaven. what question do you ask?You ask the first sentry who is that one and unique person who is way the truth and the life and through whom only it is that you can you get to the Father ? The sentry guarding heaven will tell you His name (Jesus) very easliy. Watch the them both very closely when that name is said. The sentry guarding hell will tremble when he hears that name even if he tries not to but he'll struggle to hide it, and that way you'll know who to trust. Then go through the door of the sentry who said the name cos that leads to heaven and no to the other door with the trembling sentry.

Its true haha!

"Demons will tremble at the name of Jesus" somehwere in Bible.
you ask ' would he (the other sentry) tell me this is the door that leads to heaven?'..just say his answer is 'yes'..you know it's the other door..because if he were the one who always told the truth he would be telling you the 'lie' that the other sentry would tell..but if he were the one that lied then he would be telling you the wrong answer..so you know it's got to be the other door..no matter what. obviously..if they answer 'no'..you know it's yes
you ask sentry 1 "if I ask sentry 2 is he the one guarding the way to heaven what would he say?" if sentry 1 is the one guarding hell sentry 1 would lie and say sentry 1 would say no. if sentry 1 is the one guarding heaven then he would tell the truth and say yes since sentry 2 is guarding hell and he would lie and say yes. so if sentry 1 says yes then he is guarding heaven if he says no then he is guarding hell
What door do you guard?

The sentry to Hell would point to the other door, which would be the door to Heaven, as he is lying

The sentry to Heaven would point to his own door, which would be the door to Heaven, as he is telling the truth
Ask if fire is hot or burns humans, the Hell Sentry would say no, and the Heaven Sentry would say yes.

Hope that is right =D
I'd ask, 'are you a sentry?'. The guard to hell would say no?
