“Let not my mind deny the Thought of God.”
This is another way of saying: Let me not focus away from the fullness of creation. Creation’s dynamic is always available and accessible, even in the direst of circumstances.
The thought of God is the sparkling idea that is creation: love that you can attune to inwardly, joy that you can align with inwardly, freedom and peace that you can get the feel of inwardly, and so on. Immerse yourself in those glorious, creative qualities, focus on them and align with them as you go out into the world to interact with whatever comes your way. And you will see that what comes your way speaks of love and light, and of joy and hope. As you refocus inwardly you will see that changed inner focus reflected in a changed world.
