In Philippians 3:19, what does Paul say is the god of the enemies of the cross?

Answer: Their belly

Of the enemies of the cross Paul writes: "Their end is destruction, their god is their belly, and their glory is in their shame."

“For as I have often told you before, and now say again even with tears: Many live as enemies of the cross of Christ. Their end is destruction, their god is their belly, and their glory is in their shame. Their minds are set on earthly things.”— Philippians 3:18-19 (BSB)
