Your analogy doesn't fit the situation. It would be more akin to say the bridge is destroyed. God want you to fix the bridge and cross it, but you don't know how to fix bridges and the instructions he leaves is vague and often contradicts itself. If you don't do what he says he promises to kill you or send someone else to slice your children apart and rape your wife(Isaiah 13:16)
And your absurd prison analogy is wrong as well. God created the concept of sin. God created the place of Hell. God decides who does and doesn't got to hell. God sends people to hell. You ether love and worship the monster that is the god of the Christian faith or he utter torments you forever. But you know if this god was actually loving creature he could go and say. "Bob I'm disappointed in you, You didn't believe in me. But that's okay It's not like I sent you undeniable evidence of my existence or anything. So you get to go to moderate Heaven. There's no ice cream, but only popsicles." But instead he chooses the most inhumane option. Torturing them forever.
What is it that you find so vague and difficult to understand? The gospel message in the Bible is simple and straightforward enough that a child may grasp it. All people sin, Jesus Christ paid for all the sins of the world, He conquered death and offers forgiveness, freedom from sin and eternal life. He is the bridge between humans and God. It’s not that complicated.
You can accuse God all you like of being a monster, but you do so against the scriptures and I think against truth & reality. The fact is you or any created being is not autonomous or self- existent. We cannot sustain our own life even now and certainly not for eternity. The torment will be the...
“state of separation” from the only source of life, love, joy, and beauty. God created you for an abundant, beautiful eternal life with Himself. If you don’t want it, that’s your choice.
For years as long as I can remember, I used to periodically have dreams of falling, falling down a long tunnel into complete darkness, all alone. After being saved by Jesus Christ I never had another one of those dreams. I think the reference in the Bible to “outer darkness” is a description of a lonely eternity without God.
