I am not condemning us in the sense of saying we are all bad and uniquely terrible. It is simply that we are what we are. Without God's help, we cannot be more. I can no more fly by waving my arms, than my wife cat's can drive. It's just not in us.
Human beings are flawed, imperfect and sinful by nature.
Yet there is something in us that recognizes the possibility of not being that. But we can't fly unless we allow ourselves to receive the gifts that are offered in order to make it possible. I can't fly by flapping my arms, but I can fly by accepting the gift of the laws of aerodynamics, the gifts of those who discovered them, the gifts of those who design and build airplanes. All of those things which other people do make it possible for me to do that which, unaided, I could not. Exactly the same is true in the spiritual realm.
