Believe first. Everything begins with a thought. Consciousness then brings it to reality.
We make our choices every moment...some have become so automatic that we don't even realize we are giving them power through first our thoughts. One need only know that within oneself there is the ability to have all that is desired ~ joy, love, health, abundance, peace. We need only take the time to embrace that and accept the rightfulness of it. Permit time to flow. Allow to just begin. In the willingness of such, there will be the messages. From that point, one chooses what is comfortable to embrace. Believe that your reality is your expectancy of the power within yourself to create your experiences.
We are fully capable of creating all that we desire. We need only think this, KNOW this from the depth of our isness, and then bring it to the point of matter.
What is often forgotten is the pure fact that we are indeed beautiful light beings first, then human beings by our own choice to experience such. Within the human experience there are so many lessons - always for our betterment.
