It is perfectly true that we do not know other people’s hearts. It is true that God knows. We know what we see, however.Example: I watched the **fruits **of Mother Teresa’s life. She poured out love to everyone for decades. I do not claim to know her heart, but it is reasonable to assume that these actions flowed from her oft expressed love for our Lord. If I accept that, (and I do!), I can reasonably presume to know that she is in Heaven with Him.
I saw the
fruits of a group of fanatics on 9/11/2001. Again, I do not know their hearts. I do know that if they did not repent, they died with murder on their souls. I believe that it is reasonable to at least
doubt that they are in Heaven now, because their deeds showed their hearts.
Can I be totally wrong about this? Gosh, yes. I am only

human. I make mistakes all the time. However, to use Catholic terminolgy on this point, if one person dies in a state of mortal sin, while the second has not even any venial sin in her heart, it is not unreasonable to presume that the former’s present state is less happy than the latter’s.
Therefore, until, as another post has all ready suggested, until Jesus comes back & retracts His previous statements on [hell], I must believe in it.
It is absolutely true that God **is **a God of grace. That is why Jesus went to the cross. But you see, unless God is not
also a God of
justice, that sacrifice would not have been necessary . If God,( being in charge of all things, )could have somehow forgiven sins in another way-- without the brutal torture & death of our Lord-- then He would have.Since He did not do so, & since Jesus did teach of a real hell,
I am forced to believe in it also.
Anything else would make mortal sins a joke, & the Lord Jesus a liar or deluded…neither of which I can believe.
God bless.
