Why is Sin so Terrible?

Why is sin so terrible? Because it uses God’s good commands for its own evil purposes. Let that sink in for awhile.

13 But how can that be? Did the law, which is good, cause my death? Of course not! Sin used what was good to bring about my condemnation to death. So we can see how terrible sin really is. It uses God’s good commands for its own evil purposes. Romans 7:13
