What is sin?

Do the Scriptures define what sin is?  We hear about sin and that we should not do it but do the men in the pulpits actually tell us what Yahweh Elohim considers to be sin?  His Word is very clear about this if we take the time to seek, find and obey.  Here is a short video that is very good with giving us a clear scriptural definition.

If you like the work that this gentleman does he has more videos on facebook that would give more definitions.
