Kim,
I would think that it's the difference between being saved and unsaved and you can't worship God without being saved. There are those who attend church to see and be seen. That isn't worship. God's not in it. If you can't place Jesus right in the middle of what you are doing, it has nothing to do with Him.
If you are saved, I think the Holy Spirit will let you know that you are walking where you shouldn't.
I hope this helps.
Rita
