Should I live my life based on faith or desire for success?

The heresy of the path of the ego is to do things with faith, not to succeed.

Success is in God's hands. Whether we succeed or not is out of our control. Our call is to act with faith.

In AA the first step is to come to understand that our lives are unmanageable. The second step is to turn our lives over to our Higher Power whatever we conceive our Higher Power to be. Some call this surrender. Others call it acceptance. Others, still, call it "going with the flow."

Here at UU A Way Of Life ministries we call it faith. Faith is enacted when, based on our covenantal relationships based on the seven principles, we live our lives intentionally for the shear joy, peace, and bliss of living in this way. Will it bring us success in life on the path of the ego? It's out of our hands. Will it bring us joy, peace, and contentment on the path of the spirit? Absolutely. Living in our covenantal relationships based on our seven principles brings a satisfaction and fulfillment beyond material understanding.

In AA the slogan is "Let go and let God," which can be shortened to simply "Let go," and act with Love with the intention of doing the  best right thing.
