Sins of omission. He who fails to do what he knows God has commanded is guilty of a sin of omission. A person is unrighteous when he does what is wrong. According to this verse, then, when someone does wrong, he commits sin. We should note that all unrighteousness is sin.
Men are prone to classify sin little or great, black or gray, mortal or venial.
But to God, all sin is offensive and objectionable. Moreover, He pronounces the same judgment upon all of these sinners-eternal perdition in the lake of fire and brimstone. Simply put, sin is doing what God forbids or failing to do what He commands. These two verses place everyone under the sentence of eternal death. Thus He, not being under condemnation for sins of His own, could die for the sins of others.
