Circle of sin

Tonight, something reminded me of a theme from Haibane Renmei:

One who recognizes their sin, has no sin. That is a riddle called the Circle of Sin. Think about it. One who recognizes their sin, has no sin. Now I ask you, are you a sinner?

Basicly, in one state, you are oblivious to your sin and let it pile up, in the other you constantly look for your sin and are paralysed by the search. Those who do not find their way out are said to be "sinbound". Jesus has come to pull us out of the circle of sin; he gives us the power to answer "Not anymore." How easily, though, we allow ourselves to slip back into the circle, sinning, then trying to figure out and correct our faults, when the only way out is to rely on His mercy to deal with sins past and His power to keep us in His will, the same as when we first found Him.
