It's a good thought, and it's true that even within today's church people differ wildly with what they consider 'truth'.
All I can say is...we shouldn't base our truth, or considered heresies on tradition or church history.
It should come, all of it from scripture!
Now granted even that gets us varying beliefs...but I do tend to think that a big part of that is that scripture is not being read in light of itself!
In particular regard to this threads topic, I can't help but see that the Bible does teach hell. It's not pleasant to think of people going there, but it's not pleasant to think of the current evil in our world coming to heaven either! It comes back to God being absolutely good, but also absolutely just. His very nature cannot let the blatently unrepentant come to Him. It's hard to grasp, but there are just some things about God that we cannot...and honestly, I'm glad! What kind of God would he be if my feeble mind could comprehend Him?? I trust Him, absolutely, and although the thought of hell scares me for those I know will go there, I do know that God's hand is in everything, working for His good and glory!! And we must remember that...we aren't here for our own glory, our own amazing benefit...we live to bring glory to our wonderful maker!! When we go to heaven, that's what we'll be doing...glorifying Him!
As Christians we shouldn't ever rejoyce in hell, we shouldn't ever be glad others are going there...in fact we should feel that this is an added incentive for us to preach the gospel!! Remember, the bible tells us that God is taking His time with human history, wanting that everyone would be saved! But this salvation comes only through repentance and faith in Christ. The Bible is quite clear that that is the thing needed...nothing else will do. So while it may be of great comfort to many to believe that ultimately everyone will be saved, the simple fact that many do not love Jesus cannot be avoided. In fact, many not only do not love Jesus, but actively hate Him and persecute His followers as well. Can we imagine that God would welcome them to Him, without the blood of Jesus covering them? Sadly, I do not,
But all this does not mean our God is not loving! He certainly did not need to provide us with an 'escape' plan! His amazingly deep love is shown by the brutal death of His own Son...a member of the Trinity!! We should never...never lose sight of that, even when considering some of the more difficult things the Bible tells us!
