Great question. I've looked for a precise definition.
Origins of the word refer to missing the mark, or missing the target.
Romans 5
v.12 says that sin came into the world through one man, and death through sin.
v.13 sin was indeed in the world before the law was given, but sin is not counted where there is no law
This focuses back on Genisis 3. The fall which lead to pain, suffering, and death.
Romans 3
v. 10-12 (Cited from Ps. 14:1-3)
None is righteous, no, not one;
no one understands;
no one seeks for God.
All have turned aside; together they have become worthless;
no one does good,
not even one.
2 Cor. 5:21 "For OUR sake He made Him to be sin who knew no sin so that we might become the righteousness of God.
atonement and justification. ahh bible/church words. But they are much more than that.
This verse shows how we are freed from the power and penalty of sin.
A ton of questions right now.....I'll finish this post at a later Date
Questions referring to Romans 5:13. In relation to what is sin? and back to genesis and the fall. Sin is anything unrighteous, but what is that? Is it all summed in the moral law of the Ten Commandments? Why did Adam and eve become ashamed that they were naked? Was nudity unrighteous? Or was it befor ethe fall? After Adam and Eve sinned both of their eyes were opened. Opened to what? I would suppose the difference between good and evil. Is it so? Why at that point did they run to sew fig leaves together because they were ashamed? The serpant says that they will be like God knowing good and evil. Is that true? It surely enticed Eve.
