All the great thinkers, theologians, scientists and philosophers, have disagreed on many subjects. However, there is one thought that they all agreed on. That is, that we become what we think about. Here is how Brian Tracy articulates it:
Aristotle said that we live in a universe governed by law and order. He said that everything that happens, happens for a specific reason, whether or not we know what that reason is.
The law of cause and effect says that, for every effect in your life, there is a specific cause. Nothing happens by accident. Success has specific causes. Happiness has specific causes. Prosperity and wealth have specific causes. Everything you do, or fail to do, has an effect or a result, positive or negative, somewhere in your life. Your job is to find out the cause-effect relationships and apply them to your own advantage.
The most important application of the law of cause and effect is this. “Thoughts are causes, and conditions are effects.”
In the Old Testament it says, “As a man thinketh in his heart, so is he.”
In the New Testament it says, “According to your faith, it is done unto you.”
If you want to change or improve any of the conditions in your life, you must change or improve your thinking. And when you change your thinking, you change your life and everything that happens to you. And there is no other way!
