Four questions for Christians

[Ryantology]

To say God should make us incapable of lust is to say that he should make us incapable of sin in other regards.

He hates sin so much, it would solve all his problems.

But, what you say doesn't follow. God didn't give us wings to fly, so he shouldn't have given us feet to walk?

The reason why we have the ability to sin is so that we can love God through our own merit.

And yet, it isn't really love because it's purchased with promises of eternal life, punishments of eternal death, and a situation where one party's will matters and the others' is not only of no importance, but should be ignored at all costs to satisfy the control freak. Under the Christian salvation, there is no incentive to avoid evil in and of itself. You do it because you want to be saved. You want to receive the promised rewards and avoid the promised punishments, over and above all else, and why wouldn't you? The very idea of salvation makes loving God selflessly an impossible task, yet that is precisely the demand made of you as a Christian. It makes me wonder where the morality is in all this. Seems like pure pragmatism to me. Or, perhaps, it is a poorly-conceived idea which betrays the unimaginative human agency responsible for inventing it. Why didn't Calvinism catch on? Because who is going to 'love' a God who is almost certainly going to condemn you no matter what? Would you?
