You couldn't be more wrong.
Jesus said that HE was the way, the truth, and the life and that no man comes to the Father but through Him.
If salvation were through any other means, Christ died for nothing.
It doesn't matter how good WE think someone is. God's standard is absolute perfection.
Anything other than that is sin and sin damns a person to hell.
Adam and Eve only took one bite out of the fruit of the tree of the knowledge of good and evil and for that, sin entered the world.
Disobedience to God is disobedience to God, regardless of what sin is committed. It's all rebellion.
It doesn't matter how sincere someone is and how hard they try. God allows no exceptions for *invincible ignorance* as the Catholic church does.
That's why He made it as easy as possible to become saved. Simply putting your trust in Christ alone for your salvation, and believing in Him is all it takes. Simple enough that ANYONE can do it because it doesn't depend on wealth, or status, or intellectual ability, or correct theology, or any other criteria people like to add on to it.
From the most destitute, mentally challenged, person to the richest, most intellectually gifted man, we are all so short of the perfection that God demands, that we are all in the same boat and God gives us all a means by which we can all come back into right relationship with Him because virtually anyone can understand it and avail themselves of is, no matter what impediments the world throws at us.
so the hundreds of billions of humans that God created, who had no knowledge whatsoever of who or what Jesus Christ was, are condemned to an eternity of fire and pain in Hell...go ahead and believe such nonsense if you wish, but God wouldn't create any of His children and condemn them to hell with no recourse.......period.
