Yes, I'm quite familiar with Christian mythology, and American historical mythology, too.Morality and the Law were the same and Jesus also said if you break the law in your heart, you were guilty of breaking the law. So how is your spiritual and moral life? Have you stolen, lied, had any sexual immorality, taken Gods name in vain, been envious, coveted anything, hated someone? The penalty for sin is eternal separation from God in hell. Jesus said He was the Way, Truth and the Life. That’s why He came to give His life and rose from the dead so our sins could be forgiven, we could be born again and live for God. That was Jesus’s mission. So yeah we feed the poor and generous, we help people in other countries as well and teach them skills so they don’t have to depend on other people but end up prosperous and able to help other people as well.
America has a long history of imperialist exploitation, invasion, nation-building, overthrowing governments, installing dictators, &c. It's been particularly hard on democracies, and overthrows them by any means necessary to install right-wing dictators who will play ball with American economic interests.
America does what benefits America. When America "helps people," there's a political motive.
