PIETY – dutifulness in religion; reverence for God or devout fulfillment of religious obligations
Historically and technically, piety still indicates the quality of being holy, religiously devout, or reverent. Piety implies aspects of reverence, external action, and religiosity, any of which may be well-intended or used in a showy, inappropriate manner. Jesus warns against ostentatious shows of piety in Matthew 6:1–18. Proper piety is characterized by godly behavior, and the end result is that God is glorified.
Scripture: Deuteronomy 6:5
“You shall love the Lord your God with all your heart and with all your soul and with all your might.”
“A mind full of piety and knowledge is always rich; it is a bank that never fails; it yields a perpetual dividend of happiness.”
— J.G. Brooks
