Four questions for Christians

[Paraselene]

To say God should make us incapable of lust is to say that he should make us incapable of sin in other regards.
The reason why we have the ability to sin is so that we can love God through our own merit. So that people can be good because they choose not to be evil and actively work against it, not because they have no other option.

You do realize that you have painted god as a veritable psychopath. He is one who could take away our pain, with a snap of his proverbial invisible fingers wipe away all sin, but instead he would rather watch us suffer for his own entertainment, to watch us strive for an impossible goal that he knows we cannot attain because we are simply human.

To believe that such a being is in any way good is the epitome of a delusion that will merely make the believer suffer rather than to be free of such horror.
