God could easily give your neighbor everything he needs today all by Himself, but He might not. He might whisper an idea to you and let you do or say or give something instead. He seems to care a lot more about joy than efficiency.
“A generous man will himself be blessed.” Proverbs 22:9
“[G]od will do nothing simply of Himself which can be done by creatures. I suppose this is because He is a giver.” C. S. Lewis
