Short answer, yes. Just try it. You need not know exactly how it works to make use of it, just like driving a car. Women and men down through the ages have found that invoking the divine is a useful way to make things happen in their favor.
Long answer, yes. But if you're like me you need to know that magyc is not only possible but plausible. This next section is long and involved so you may want to do it in a couple of sitting, like chapters in a book.
For your long answer then, I direct you to the Universe at large and the sub-atomic Universe within. First let your mind journey outwards into the cosmos. You will have to travel at the speed of light. That's as fast as anything we know travels-- 700 million miles an hour in the vacuum of space. That means light can travel around the world 7 ½ times in a single second. Imagine how far light could go in a minute (448 times around the world), in an hour (26,889 times around the world) in a week, a month, and finally a year. This last time span, a year, is known as a "light year" and it is not a measure of time but rather distance: the distance light can travel in one year. Of course we can no longer use the circumference of the earth as a yardstick, the numbers become meaningless. Instead, to give us an idea of cosmic scale we can say that the nearest star is 4.3 light years away. That's a lot of miles away.
To get a little better idea of the scale of the real universe, the Milky Way, our galaxy, is 100,000 light years across. Light would need 100,000 years to go from one side of the galaxy to the other. But that's nothing compared to the size of the universe at large. Scientists believe that the universe is 13.7 billion years old. How do they know? Because we can only see bright objects out to 13.7 billion light years in every direction. That means that what we can see of the universe is 36 billion light years across. Boggles the mind, doesn't it?
Well, hold on because that's only what we can see because light hasn't had time to arrive on earth from further away (and why they can estimate the universe is 13.7 billion years old) Beyond that lies most of the universe. It's estimated that if what we can see of the universe were shrunk down to the size of a quarter the part we can't see would be the size of the earth itself.
To that add that fact that even the part we can see and detect is estimated at only 5% of what's really there-the rest being Dark Matter. No one knows what that is. But it's there.
Meanwhile, in the other direction: inward, things get smaller and smaller on the same mind boggling scale until the smallest theoretical particles are the size of nothing. This, however, is the same nothing the universe was created from. When my mother, a Catholic, hears someone say that the universe was created from the Big Bang, she always asks them who created the Big Bang. If you don't have an answer she will say you can't create something from nothing, only God can do that.
Okay, but the universe may not have been nothing in the beginning. No thing but not nothing. In the 60's a physicist Peter Higgs theorized that the entire universe was actually pure energy. This energy apparently can weave itself into subatomic particles. He even named the as yet to be found subatomic particles the "God Particles". This Universal energy pervades everything at all levels from the macrocosmic to the microcosmic and everything in between.
Energy? Like in a battery or running through the wires by which we now communicate? Yes, and every other form of energy going--all energy. We know know energy on a daily basis. I'm using it now. But none can say what it really is. Oh, we have equations to predict how energy will behave, hundreds of them, but they don't say what energy actually is. Einstein's E=MC2 is just such as equation that says there's a great deal of energy locked up in very little matter. It's why a couple of pounds of uranium can blow up a whole city.
