Good Morning Doug,
I don't know exactly where your coming from, but I'll give it a try. Ray discusses this distinction between a Sin and Sins(plural), but I couldn't find it, maybe another member can share that, but here are the Scriptures.
1John. 2:1(Please read, " committing a Sin"), add to that 1John. 1:8-10( " making the statement, we have no Sin, we are misleading ourselves), please read passage, I just paraphrased some points.
Now, please read 1John. 3:4-10; This passage demonstrates a practice of Sin or being consumed by Sin. Sinning is a way of Life, no remorse. As an example, someone who continually cheats on his Wife without any remorse and it becomes a practice and the sinner doesn't care or sincerely ask forgiveness, it's a pattern.
See the distinction or difference, one is consumed by the pattern of sinning, maybe Adultery as an example in contrast with the person that did it once and is truly sorry and seeks forgiveness and has demonstrated true remorse for their actions.
Hope this helps, I know Ray refers to committing A SIN comparing that with BEING CONSUMED BY SIN.
In Gods Love, Samson.
