Confusing “Beliefs About” with “Beliefs In”

There are two types of beliefs: beliefs about and beliefs in.

What we believe about is information, cold and infertile facts, motionless and dead. I believe about Mt. Everest, that it is [about] 29,000 feet high; and I believe about air, that it is [about] 21% oxygen. I accept these facts, but they are lifeless and sterile.

What we believe about is like unread books on the dusty bookshelves of our mind. They may be an enviable collection, but they are unopened and unproductive.

What we believe in is our reality; it is an inner force, something fresh and insistent, an active, pregnant pressure. What we believe in births an inner life that propels us.

What we believe in is like movies played on the screen of our hearts, moving us to tears and laughter. What we believe in becomes the script of our lives. It is our reality.

It’s possible to confuse beliefs about with beliefs in. One of the biggest lies we buy is we think we believe in God’s love when we really only believe about it. And it is the difference between living a cold, dusty, barren life, or living a hot, vibrant, fruitful life.
