Yes, he could, but the question is will he and often the answer is no. What would we have learned as children if our parents had bailed us out every time we got into a mess - a term paper we didn't write until the last minute, or the candy we were supposed to sell for the school library fund but ate it instead (yeah it's true :-).
Or more serious situations. Life is a learning process and a good parent stands by supporting the child, but also letting them learn a little about life and how to live it.
I believe God does this as well.
