A Christian must believe that…

Man is a Sinner fallen from original righteousness and a high, intelligent and responsible place as head of the present creation. Apart from God’s redemption grace is lost. Man is not the unfortunate victim of environment, one who through self-culture can make good.

Romans 3:23-25
