What we take to be true is our reality. That journey and everything else that comes into being begins with the first thought. Considering Zukav's thread, it follows that if our thoughts entertain the notion that thought is not central to creating reality or influencing events, then certainly that thinking will become reality and thus have no power. Skeptical and doubtful thinking lose its power to affect change. If thought is the fabric from which reality is made, then faith and intention become the mechanism by which we focus and project thought.
Faith is the opposite of skepticism.
Faith is empowering a belief that is not empirically proven. By faith we understand that the worlds were framed, fashioned for their intended purpose, by the word of God, so that what we see was not made out of things which are visible. Our beliefs come from not so much scientifically supported studies, but from our experiences, education, thought patterns and thus vary from person to person. Delightfully, this gives hope. Faith-charged beliefs create our realities.
