I will find serenity to accept the things I cannot change,One of the things that we must admit to ourselves - the unbeliever and believer alike - is that we humans can draw inspiration from secular and religious sources. It does not mean that the motivation for the words (religious or not) confirms or disconfirms the reader's world view. It just confirms that the words and acts of others can touch us, regardless of the motivation that the other has in performing them.
courage to change the things I can,
and wisdom to know the difference.
I like the Serenity Prayer - it is simple and direct, and speaks to a need that reoccurs in my life - I need serenity, courage and wisdom all the time.
In keeping with my disbelief in the supernatural in general, gods more specifically, and the specific god referred to in the Bible, I believe it's consistent to remove the word "God" from that prayer, while continuing to use the words as a meditation to achieve the same result. Thus - The Serenity Meditation.
