If you are having a hard time with Paul's teachings one way to clarify them is to ask yourself what can't Paul be saying. He will never and can't be ever saying anything contrary to YHWH'S laws and commandments that's the first thing to understand. Then if you still are having a hard time understanding what he is saying look at the context. Then if you still don't understand then put it on the shelf and wait YHWH will teach you and bring understanding if you need it, if not he won't. Something to think about.
