When you say 'God bless him' how does god bless him?

Answer 1

This idiom is not meaning a specific blessing such as many cultures have - bless you with many children, or 1000 blessings on your house! When an American, especially a southern American, says "Bless him," "Bless you," or even "Bless your heart," they are simply stating a wish that good things happen to that person. Usually, they will use the phrase when talking about someone who is going though a hard time. It is often just a vague expression, similar to "poor thing" or "unlucky fellow."
