Before a person can intelligently believe in Christ, he has to be aware of the guilt of his sin. He also must face the fact that God is righteous and that He judges sin. This is further defined in verse 9, “in regard to sin, because men do not believe in me.” An unsaved person needs to realize that while he is a sinner, as all men are sinners, this constitutes only a part of his condemnation before God. The one sin that prevents him from entering into grace and favor with God is the sin of unbelief.
