the door deciding your eternity

Riddle
1 Door leads to Heaven
1 Door leads to Hell

Both doors have a guard. One of the guards always lies and the other always tells the truth. You can only ask 1 question to one of the guards. What question will allow you to reason correctly which door is the one to heaven and which door leads to hell?
PS- this question must work for both gaurds.

As k either guard, "If I asked the other guard which was the door to heaven which would he say?" Whichever door he indicates, choose the other one.

turn to one guard (it doesn't matter which one) and ask:
what door would the other guard tell me to go through to get to heaven?

then choose the other door - it will always lead to heaven.

if you ask the truthful guard, he'll tell you which one the lying one would advise. If you ask the lying guard, because he lies, he'll point to the same door.

Good answer monor but I think Dundurn just beat you to it.
