God knows everything, but this does not eliminate man’s responsibility to confess his sins. Failure to do so forfeits God’s practical forgiveness.
Most people view sin as a private or earthy matter. Yet, every sin is against the Lord. In truth, men can sin against the Father, the Son, and the Spirit.
Man’s conviction is a work of God that begins within a man, hidden from the view of others. Yet, that work ultimately manifests itself on the outside. As the apostle Paul reasoned with Felix concerning righteousness, temperance, and judgment to come, the Spirit of God took the sword of the Spirit (the word of God) and worked within Felix. Though Felix’s conviction did not lead to his immediate conversion, it visibly affected him by causing him to outwardly tremble. The book of Daniel tells us that the Lord interrupted king Belshazzar’s party and caused his knees to smite against each other (Daniel 5:1-6). The Second Book of the Kings tells of Josiah’s conviction that was manifested through his weeping and the rending of his clothes (2 Kings 22:19).
Once confronted by the presence of the Holy One, man’s personal viewpoint always becomes increasingly realistic. By all standards, Job was a good man, yet the presence of God caused him to abhor himself “and repent in dust and ashes.” Conviction always magnifies the greatness of God and reminds man of his own vile nature. Ezra’s conviction was described as heaviness (Ezra 9:5) which caused him to rend his garment. That conviction humbled Ezra to the point where he said, “I am ashamed and blush to lift up my face to thee, my God: for our iniquities are increased over our head, and our trespass is grown up unto the heavens” (Ezra 9:6).
This world, though it consistently fails to recognize and know the Lord, should consistently recognize Christ's conversation through the life of the believer. Our conversation should always match, or become, the gospel of Christ and the new life that we have in Him. Our conversation should be holy because the Lord is holy (1 Peter 1:15). In 2 Peter 3:11, we learn that the dissolving of this world ought to cause us to walk “in all holy conversation and godliness.” In other words, our practical Christian life should resemble the change inside of us that took place at salvation. Others should see the Lord Jesus Christ in our actions and in our way of life.
God is as equally concerned with what we do as to how we do it. It is not only important that we have the right kind of conversation, but that our conversation be based on “simplicity and godly sincerity.” In other words, our conversation should be genuine and never extravagant. People behave for different reasons. Sometimes those reasons are godly, yet at other times they reflect ungodliness. Anyone can feign a good conversation for a short period; however, only with the Lord's help can one's motives consistently match his actions. Paul not only sought to have his conversation right before the Lord, but also desired a genuine change of heart to bring forth the proper conversation.
