God's work

Actions that are virtuous, necessary, and meaningful (thus in line with the teachings of God and the Bible). Sometimes used humorously or sarcastically. You're doing God's work with these abused dogs—they are positively thriving in your loving care. Feeding the poor is God's work, that's why we go volunteer in the soup kitchen every week. A: "My company designs ad-blocking software for PCs and mobile phones." B: "Ah, doing God's work, I see."
