Romans 3:5-6 // I Speak As A Man

Romans 3:5-6

5 But if our unrighteousness commend the righteousness of God, what shall we say? Is God unrighteous who taketh vengeance? (I speak as a man) 6 God forbid: for then how shall God judge the world?

If there were no serial killers and pedophiles we would have a lot more trouble convincing people that sin is a bad thing. The depths of sin that many people fall into demonstrates that God and his law is right and rebellion against him is wrong. The most pronounced case of this is the crucifixion of Jesus, where sin showed that it would even lead people to kill God himself.
Paul writes: "I speak as a man". He does this kind of thing quite often, leading to confusion among those who refuse to compare scripture with scripture to clarify their interpretation of his theology. This may be what Peter was talking about in 2 Peter 3:15-16 and he was right, misunderstandings of Paul's writings are the source of the most popular heresies.
Writing from the perspective of an unconverted man, Paul poses the question; If God uses my sin to show his own correct position how isn't God unfair because he punishes me for helping him out? No, no! God needs to bring justice to the world, but if everything that happens is to his credit (shows God is good) that only proves God is in fact good, it does not prove he is pulling the strings to make people sin so that he looks better. This world needs justice, and Jesus is going to bring it some day soon. Are you a source of injustice or a source of justice? Are you a source of mercy or a source of oppression? Jesus is the master teacher, he can transform your life and make you like himself. Submit your life to him and let him turn you from a rich ruler to a contented peacemaker.
