Sin is not something man does by accident. It is something man does or allows based upon an unwillingness to stop an act before it becomes sin.
Scripture provides examples of specific sins; however, no example DEFINES sin. John's first epistle defines it as the transgression of the law.
Conviction testifies of guilt and transgression. It testifies that God is just while man is vile. It testifies to the gap of righteousness that exists between the two. If men were righteous apart from the Lord’s help, the Lord would never need to convince men that they are transgressors of His law. When men violate or transgress the law of God, the Spirit of God uses that law to convince those guilty that they are wrong and need to make things right with the Lord. The very presence of conviction confirms man’s guilt. It cries out that I am wrong and God is right. Perhaps this explains why in these last days, fewer seem interested in experiencing the convicting work of the Spirit of God.
