Yes, God wants us to take care of what He has entrusted to us. Good stewardship, then, is making sure that we and what we have are to the glory of God. Good stewardship is seeking first the Kingdom of God and His righteousness. Covetousness sees stuff for me. Stewardship sees stuff for God and for others.
Covetousness clenches things in a selfish grip.
Stewardship holds it all in an outstretched, open hand.
