I was alive without the Law once: but when the commandment came, sin revived’ (Romans 7:9) “So it is with the work-righteous and proud unbelievers. Because they do not know the Law of God, which is directed against them, it is impossible for them to know their sin - Martin Luther

“I was alive without the Law once: but when the commandment came, sin revived’ (Romans 7:9) “So it is with the work-righteous and proud unbelievers. Because they do not know the Law of God, which is directed against them, it is impossible for them to know their sin. Therefore also, they are not amenable to instruction. If they would know the Law, they would also know their sin; and sin to which they are now dead would become alive in them.” 

Martin Luther
