If the only prayer you ever say in your entire life is thank you, it will be enough.
In this day, I can be grateful. It is a given that all is palatable with gratefulness as gravy.
For the things that I have control over, and feel empowered to do today, I am grateful. For what I have no control over, and feel letting go is difficult, I am grateful. For free will, and what God has given me and all others within this human experience, I am grateful. Whatever is, gratitude can change it for better.
