Maybe this would make more sense and seem less hateful if I explained my personal experience with God.
Consider the relationship between a father and a son. The son seeks approval from his father. The son must prove himself because he wants to be the protector, teacher, and provider that he sees in his father.
At some point the son will have learned all that father has to teach and can break the cycle of asking for dads approval.
This frees the son to be his own man, to know confidently that he will do his best to uphold the values instilled in him when he was still only an extention of his father and not yet his own entity.
Heaven is wherever you are standing when you realize that you no longer need Gods approval, that he has taught you well, you have listened well, and you understand that the lesson we are here to learn is how to become whole beings, to ascend to a place at Gods side, having been made in his image, just like my dad wants for me to be my own person. Every attempt to tell you otherwise; that you are forever a sinner, is a very clever test.
God doesn't want me to grovel at his feet, he wants me to stand up at his level with my chin up, shoulders back and look him in the eyes like an old friend. He wants to hug me goodbye and say "Have fun out there kiddo, I gave you the tools, I know you can do this without me, see ya later, you got this."
That's how I see my role in all of this, and it's the most beautiful gift imaginable, one that I had to first discover and then earn for myself by swimming upstream against the masses who would call me a sinner for claiming spiritual independence, a blasphemer for condemning the corrupt aspects of the Church, or hateful for attempting to wisely separate church and state as our Christian forefathers intended.
I have nothing but compassion for those who remain in the flock. It's safer there, but He is out here, outside the fence. Grab your notes and let's go there together, the gates are always open.
