Here's an example of how one might look at these innocent "rituals" as we are calling them.
I'll give a make believe example of something that might appeal to myself, you can easily make your own example.
Let's say I decide that I will start spending my day of rest in my remote mountain cabin. I decide, that I'll take bread and wine for obvious purposes.
At some point, I may read the following instruction in the bible:
"Don't eat upon the mountain(s)"
And I may interpret it as:
"Don't let the surety of your personal salvation be your sustenance"
Further, there are bread and even water in particular mentioned.
I then think: "well, that's exactly what I've been doing physically for the last several weeks, but... I know I have not had that self-victory attitude, so I haven't been guilty of this, yet, I did not seek this sign, so it may be a reminder. Now that I have recognized this, should I continue innocently as I was, with one ritual, or do I change my sabbath stay at my cabin to one of fasting? And, will I be able to endure a fast and simultaneously call it rest?"
I do not believe I must "choose correctly" if or how to change my "ritual", because I would never have planned such a thought process. I never considered it a "ritual" to bring about a purpose, and if I change it, it will be a reflective change, not an intended "prophetic" change. Either way I proceed in the flesh, will bring no harm, and my intent is my best effort at righteousness, I believe God is happy with the intent.
Therefore, I believe "Mother Teresa" for example, probably carried more in her Spirit while she prayed the rosary than most who do it because it is "required." Based on my observation of her fruit.
