If God had drawn the world from pre-existent matter, what would be so extraordinary in that? A human artisan makes from a given material whatever he wants, while God shows his power by starting from nothing to make all he wants. 146
Catechism number 308
The truth that God is at work in all the actions of his creatures is inseparable from faith in God the Creator. God is the first cause who operates in and through secondary causes: "For God is at work in you, both to will and to work for his good pleasure."171 Far from diminishing the creature's dignity, this truth enhances it. Drawn from nothingness by God's power, wisdom and goodness, it can do nothing if it is cut off from its origin, for "without a Creator the creature vanishes."172 Still less can a creature attain its ultimate end without the help of God's grace.173
