I admire OP for questioning your belief
My short answer: The bible doesn't make sense.
It's not a word of some divine creator bullshit!.... Gibasa na naq ang bibliya from cover to cover, from old testament to new testament. It's just some stories copied from ancient sumerian books.
To think that billions of people fall for this shit scares me.
Religion is some bullshit.
When some voices you hear that you will offer your son as a burnt! sacrifice. The answer is NO!, you idiot Isaac!
If you are in doubt, Read something on
