Using righteous judgement. You admitted you do not know the Biblical definition of sin as you avoided repeatedly a direct answer to my direct question.
Again, thank you for your time.
That's not true, just because someone doesn't answer a question, it doesn't mean that that person doesn't know the answer. That's not logical. That doesn't make sense. There could be other reasons why the person didn't answer the question, as in this case; I didn't trust you. You seemed like you had ulterior motives, which it turns out that you did. You are being rude to dismiss me the way you are trying to.
To satisfy your question, however, I'll explain to you what sin is; but I'll keep it short. There are various things which one should not do. If one does those things, that is sin. You could call it doing wrong, doing evil, doing something bad. There are the Commandments, which if one violates, it is sin. There are what are known as vices, such as lust, gluttony, pride, greed, and so on, that if one commits, it is sin. Any kind of offense is a sin. An offense against God, an offense against someone other than God, they are all sins. Now, I'll wait to see if this meets your approval, since you seem to have a chip on your shoulders about whether I know what sin is or not.
