Yes if we break the law at one point we are guilty of breaking all of it. In public it is not harmless others with various weaknesses might be tempted, confused. And what about children so it is not so harmless, what about the harm to myself or to my poor wife before she was ill. It is not harmless. Jesus brought a New Testament so many of the Old Testament laws were irrelevant - no need to sacrafice lambs, Christ died for us, many dietary rules went by the way as well. I am no authority a Minister could probably sort all of this out. That is beyond me. It is true we are not to judge others, but we are to repent and work out our salvation soberly - fear and trembling. To many this may seem trivial, but it is not. Perhaps it was pointless to post this.
