“why would god help?”
WHY?
All people sin. Therefore all nations also are sinful. We all are in need of a Savior.
“You know nothing at all, nor do you consider that it is expedient for us that one man should die for the people, and not that the whole nation should perish.” (John 11:49-50) The death of Christ on the Cross becomes the Savior for the sin burden of the whole world.”
We cannot expect the world to operate in any other way other than that which it presently does. They have made a god made in their own image and after their own likeness and i magination and are held captive by the god of this world. (2 Tim 2:26).
