Why is Christ's death considered a sacrifice?

[Neo-Scholastic]

You have the burden of proof to show that a perfect world is even possible...(sound of crickets)

Maybe it's not possible. This would mean that either your god has crippling limits to his powers and knowledge and capability,...

All knowledge is limited to what can be known. Since the future does not yet exist, it cannot be known. No one, not even a god that knows everything that it is possible to know can exactly predict all the outcomes of someone else’s actions. As such, the actions of free agents may inadvertently bring about harm and suffering, absent moral accountability. Our ability to love depends on having the freedom to choose whom we love. What you see as "crippling limits", I see as the space wherein God withdraws his Power to make a place for Love to exist.

I haven't seen you prove your god's existence yet, and I'm sure I've asked you more than once.

And I've proved said evidence that you have ignored more than once. You bore me with your continued whining about how God didn't make a perfect world, since you cannot prove that a perfect world is even possible.
