Satan's Subterfuge

Does God want us to focus on our sin, or does He have something else that we should spend our time focusing on? Does the action of concentrating on our sin (and how terrible it can make us feel), create within us a spiritual maturity, or a spiritual poverty, born of false piety? Are we struggling to gain something we already possess, but are simply not aware of it yet? Satan benefits greatly by keeping God's children blind to the many blessings that are ours in Christ now.
