There is a metaphysical Law of the Universe that says ‘that which is like unto itself is drawn’. Jesus put it this way, ‘It is done unto you as you believe’. Proverbs says, “As a man thinketh in his heart, so is he.”
What it basically comes down to is that what we think about, we get. Our lives takes the shape of our predominate mental atmosphere. Persons, places, conditions and experiences mold themselves around our lives according to the patterns of our thought.
This is pretty powerful stuff. What it means is we have way more control over our lives than many of us think. To change our lives is really as simple as changing our thoughts.
