Self examination is important and biblical. But there are two ditches on each side of self examination.
First self examination is done with bible open, prayers made for God to reveal what the Spirit of God wants to deal with. Many sins are works of the flesh that simply need acknowledged, confessed and heartily repented from. But there are other sins like "besetting sins", those sins that knock us down, or sins which we trivialize but are genuinely a dishonor to the Lord. For those sins, just ask your wife or hubby, or your best friend, or maybe a godly leader who looks over your life. They can bring perspective.
The real issue in self-examination is "are you in the faith" and are you fruitful. We should judge in three different areas. Doctrine, fruits and works. The spiritual man judges all things, so in those areas examine yourself; and in respect to knowledge, do you practice what you know?, in respect to fruits, genuinely look at the way in which you express your faith in trials and with prosperity. In respect to works, what are your motives and how do you see yourself depending upon Christ?
The ditches are introspective condemnation and apathy. Apathy kills passion, or rather has killed passion and your walk with Christ will show one major trait...boredom. Boring bible reading, boring prayers, boring fellowship, boring faith, safe easy going living. In short, a life that has no sacrifice and no interest in displaying a deep consecration to God's kingdom. Introspective condemnation is simply wallowing in the sins and failures of your carnal heart. Its a woe is me mentality that is defeated and ashamed. Not because of great conviction of sin, but because the person who does this is not using their faith to overcome, but rather is expressing pity and discouragement for their situation. In short they are waiting for God to do what they must do. God requires the exercise of faith in the power of God's word and Spirit. When these are ignored, self-condemnation will arise and the sins you fear will be constant companions to you. The victory is believing you have been justified, believe God has made you righteous and that God is ever willing to empower you to live daily in victory.
