I think what I find hard to believe, is that others will judge people who don't believe in the trinity as not belonging to God and they say that they belong to Satan and are going to hell. Yet this isn't taught anywhere in the Bible. I couldn't condemn anyone to hell, and I have hope that everyone will enter into heaven. I don't understand how people have become so high and proud that they can look down on others who love God in this way, and they don't know their hearts.
There are those who believe that because others believe as they do they are saved, but many could have a heart very far from God, it's not what we say, but what we do that shows how much we love God. And he is judging all of our hearts.
Jesus taught us to love and forgive, show kindness and mercy and bring the love of God to others. He didn't teach us to condemn each other to hell.
I believe that heaven and hell are a state, and that we can enter into them in the here and now, hell being in outer darkness under the control of Satan, and heaven being in the glorious light of God and our hearts being protected and cleansed by him, and the way to him us through Christ Jesus. Many think this world is the be all and end all, with their "you only live once" mindset. But this life is temporal, and to know God is to walk in the light and once we know God, then this world and the works of it should mean nothing, our flesh should be dying, (which is death to self) and we should be living by the will of God, wanting to please him, being a living sacrifice and bringing the love of God as Christ to all we meet, regardless of who they are, or what they believe, or what they do to us. We are to show them the love of God which Christ Jesus showed perfectly and he's our example and God is judging us on what we do and what we say.
God loves us all, I couldn't condemn anyone to hell, I'm just flesh and it's not my place to do so. I hope that God forgives those who do this.
What they fail to realize is that they are still within the framework of a "Law mindset", as if to say, "You do not believe this, you have not done that, therefore you are judged as going to hell", and in this they show themselves nothing more than modern day Pharisees imprisoned in the gall of bitterness and probably also the bondage of iniquity. That is not to say my judgment, (or to single anyone out), but the tree is known by its fruits. If it speaks and judges like a Pharisee it is probably a Pharisee regardless of the outer trappings and shiny whiteness on the outside of the cup.
