George Bailey is a good man, doing good things. But being a good person and doing the right thing wears him out. When he gets to a breaking point, he's given a vision of the real impact of his life. That changes his perspective on everything. Likewise, we are created to have a purpose worth living for. We so often go through life exhausted from trying to be good enough. Jesus came to establish a Kingdom that gives us a purpose worth living for, which can change how we see it all.
