"Nothing comes from nothing. Nothing ever could!"
The profound words of Julie Andrews are not merely charming lyrics, but also a straightforward explanation of the law of causality. Causal Law, by definition, states that it is necessary for everything that happens to have a cause. Nothing comes from nothing. This law has been around, literally, since the beginning of time. At creation God caused all of time, space, and matter to be brought into existence; or, as it says in Genesis 1:1, "In the beginning God created the heavens and the earth."
The law of causality applies to everything that ever began, including the universe. To say otherwise is folly. To deny Causal Law in regards to anything at all is to deny reason. Logically, effects have causes. A spilled beverage cannot have toppled itself - something caused the glass to overturn. Analogously, the universe cannot have created itself. There must have been some sort of entity to cause it to come into existence. Considering when the universe began, time, space and matter began with it, it makes sense that the cause of creation was not so much a something as a Someone.The universe is finite, and its origination was also the beginning of time. The Originator then must be an infinite being not affected by time.
Evidence of God in the Causal Law is also seen when one looks at the complexity of the universe. Every detail of every element of our universe is so perfectly meticulous, even the smallest variation would cause disaster. The design of nature is so precise, it is quite obvious there must have been a designer; not merely to create, (though that is a wonder in and of itself,) but to make sure His creation continues to work the way He intends it to. The universe, much like a sailboat, needs someone to steer it, or else it will crash. Were God not in constant and complete control of all things, the universe would inevitably self-destruct.
God controls all the inter-workings of space, matter, and time. He controls all of our solar system and our world. This includes natural disasters, the relationships of the nations, and how many flowers are going to bloom in your garden this year. As He is omnipotent and infinite, God knows all that has and is going to happen. He knows exactly who the next president of the United States will be, how the political situation in Egypt will affect the rest of the world, and where Amelia Earhart's airplane went down. He knows all there is to know about the universe because He created it. Everything He created works in order to fulfill His purposes. He knew what He was doing when He caused time, space, and matter to be created out of nothing. He has a plan for everything. Romans 8:28 says "And we know that all things work together for good to them that love God, to them who are the called according to his purpose."
His causes have wonderful effects for those who love Him.
