Perfectionism in this active life is the worst sin. The problem is, we are inclined to our own depths of sin. And we don't like the sin that is revealed to us. We are biased by our own love for being fair. Hence we waste many times. We waste time comparing ourselves to others. Of course, if we get enough people to volunteer to participate in religious practice, we inevitably produce a repressive society of legalism. How many of us enjoy adequately acknowledging the moral depravity of our own ways and reflecting on what we are doing? But feeling hardship as a direct result of our disobedience to really commit sin. People cannot do good, and if they achieve a certain level of goodness, they would think better of themselves than they are. Which is simply the worst sin of evil pride. 

Sin inevitably begins in the life of thoughts, and it is not just lustful, greedy, and murderous thoughts that are repulsive, but the ordinary way under the curse without the means of being righteous before God. The ugliness of sin is shown simply by thinking that we traditionally practice a certain orthodoxy and have become God's official spokesman. We develop a religious acceptance, we feel capable of doing God's work within ourselves. Our own obedience endures the dangerous time when we are most sinful because while we are on this earth sin is present in us, we urgently need to see ourselves as exactly as God marks us. We, the more sinners we are sincerely convinced. And by that I don't mean that we just pass on the Reformed dogma. 

We kill sin, go to the God of the Word, soon we will feel like the main sinners, and if you think that the negative attitudes we experience when we see ourselves as we undoubtedly are, then we get depressed and does not discourage very wisely in the present from seeing ourselves for what we are ends when we pay careful attention to who God is. We thought we were alone in this fight, we would probably speak interpretative about turning away from sin. But those who turn away from sin really feel that their moral sin is beyond their own ability to overcome it.
