He believes salvation is his responsibility, and sees it as a reward for his good deeds, or at least a reward for his right desires/will.
If he sees he has overcome certain sins, he is either, 1) noticing the work that Christ has done in him and is taking credit for it, or, 2) the sin has taken on a new form and he no longer recognizes it. His praise to God is an effort to prove himself righteous and holy in God's sight.
He does not rely on Christ, though he may think he does. He teaches others that their desire for righteousness is what pleases God, and what get's God's attention. He teaches that their lifestyle and their choices will determine their level of righteousness, or that it will determine their standing with God. His sermons are full of exhortations to repent and do good, and advice on how to go about doing it. They are full of challenges to be better and do better. They are motivational but bear temporary fruit.
This man is always striving and eventually gets tired. The grace of God will always renew him, however he suffers much damage and has the potential to damage others merely by his oppressive, sin-focused doctrine. His heart is heavy and full of sorrows; sorrows for the sin in his own life, and for the sin in others'. What he mostly sees in others is their failures, because he is consumed by his own sense of failure. The leaders in his ministry who adopt his teachings are hyper-motivated to do good deeds, but this motivation is guilt-driven, and full of striving to measure up, and they eventually burn out. They become scarce and hesitant to volunteer. They don't stick around for very long because their own strength does not last.
Victory over sin can only be accomplished by Christ. The man who realizes this, and merely accepts that he did nothing to accomplish it except to receive it by the grace of God, is the one who truly experiences freedom from sin. He knows that any good he has ever done was Christ acting through him. This man can truly proclaim victory over sin in all humility.
He realizes that salvation is a gift, not a reward for good deeds.
If he sees he has overcome sin, he knows that Christ alone has done it, which causes him to feel profound gratitude and appreciation towards God. His praise to God is deep, heartfelt, refreshing, ecstatic, spiritually charged, and often leading to mystical experiences. He cannot see God as anything other than wonderful.
This man relies on Christ alone for his character, his self-discipline, his understanding, his doing good deeds, and his desires. Christ does not give him strength, but IS his strength. He may look like the first man in all respects, but he is truly free. He teaches others that their righteousness does not come from their thoughts or their actions or their choices, but that Christ is their righteousness and therefore their standing with God will never change. He never questions whether or not he is worthy of favor or whether or not he has spiritual authority because he knows that he himself did not generate his own worth, nor did he generate his own authority, but that his worth and authority are in Christ. His sermons are always about Christ. They always point to what Christ has done and who He is. He is not focused on sin, though he may struggle from time to time, because he knows the responsibility of taking away sin falls on Christ (John 1:29).
He enjoys God fully because he's not tired or burned out. He hasn't been fighting against sin out of his own strength, but has been trusting God to take care of it. He hasn't been focused on his own performance, which leads to condemnation, but is focused on God's performance, which leads to confidence. He's been resting in the truth of God's word and has been experiencing true joy. He doesn't need to prove anything to God or to anyone else, because He identifies himself as a son of God.
He's no longer focused on fixing himself and is freed up to enjoy the deeper things of God. He knows the truth, which has set him free.
