Q27: What do you understand by the providence of God?

A27: The almighty, everywhere-present power of God,[1] whereby, as it were by His hand, He still upholds heaven and earth with all creatures,[2] and so governs them that herbs and grass, rain and drought, fruitful and barren years, meat and drink,[3] health and sickness,[4] riches and poverty,[5] indeed, all things come not by chance, but by His fatherly hand.

Q28: What does it profit us to know that God created and by His providence upholds all things?

A28: That we may be patient in adversity,[1] thankful in prosperity,[2] and for what is future have good confidence in our faithful God and Father, that no creature shall separate us from His love,[3] since all creatures are so in His hand, that without His will they cannot so much as move.[4]
