God sends angels when you least expect them. And in the most wonderful ways. It's like a father teaching his kid how to cycle. He lets the kid go, even if the kid thinks she's gonna fall, lets her learn to strive on ahead anyway, and when she really is going to fall, he knows, and catches her. So that no matter how alone she thought she was, she could never have been safer. Or more lovingly and carefully watched over.
Even the sparrow.
