I know you mean well, and I can see it in your writing. But you only raise more questions than you answer. Especially when you say that I don’t know anything about Christianity. On the contrary, I do know something about it. Your concern appears to be that I don’t know what you know about Christianity.
So God’s love is a gift? Why then, would Christianity teach that there is a place called “Hell” and that you go there if you don’t behave properly? That sounds like something to earn there.
And since we’re only human and prone to error, why do we need to be forgiven in the first place? That sounds like something else to earn there.
The question is not whether I should decide to receive the gift of God’s love. The question is why do I even need to receive God’s love in the first place if he’s already given it to me? The mere decision to accept God’s love implies effort. That sounds like something to earn there, too.
I offer these questions in all sincerity. If there is a god, I suspect it is far greater than a book can possibly describe, and that we’re not even remotely capable of comprehending what that god is. That is why I have so many questions.
