Why is Christ's death considered a sacrifice?

[Ryantology]

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.

The god who comes from outside time and space and created time and space doesn't know what will happen in the future?

This sort of discussion invariably goes one of two ways:

1: Atheist questions god, Christian attempts to impress everyone with the limitless capabilities of God.
2: Atheist notes a reasonable expectation of a God with limitless capabilities, Christian insists that there are limitations which make these expectations unreasonable.

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.

Do you have kids? If so, when did you sit down, think about whether or not you loved them, and decide that you did? Could you simply change your mind and not love them? I ask because, while there are people I deeply love, none of this ever happened as the result of a decision, and I'm pretty sure that I'm not the one with severe emotional retardation here.

And I've proved said evidence that you have ignored more than once.

Show me where you've objectively proven the existence of your specific God and I'll get on the phone with the Nobel Prize Committee right now. Really, go do it. You claim to have made the biggest human accomplishment in all history and I want to make sure you get the credit for it.

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.

I don't claim that it actually is, you know. I can't. It would require the existence a perfect and all-powerful creator god, and you can't prove there is one.

I'll lay down the challenge right now: If you can prove that your specific god is objectively real, then I will set about to prove the possibility of a perfect world the minute I'm off the phone with the Nobel Prize people. If you can't, then I have no reason to bother and I'm going to never miss an opportunity to remind you of your impotence whenever you make the assertion you failed to prove.
