We all know that we are not God and that he ought to be worshipped, so are without excuse (Rom. 1). But by nature we reject the Creator and worship the creation (Rom. 1). We also tend excuse our own sin (Rom. 2). "All have sinned, and fallen short of the glory of God." (Rom. 3). "The wages of sin is death." (Rom. 6). But if we believe in Christ, we shall be saved. (Romans 10) because of Christ (Isaiah 53, Romans 5).
