“I am the LORD; that is my name! I will not give my glory to anyone else. I will not share my praise with carved idols.”
Isaiah 42:8

Among all the religions and philosophies, how do we know Christianity is true? While there are many ways to address the question, let's begin by saying that Christianity makes sense of the world around us. In other words, it presents the most correct worldview based on the world in which we live. There are three worldviews that lie at the foundation of all religions and philosophies: theism, naturalism, and pantheism. Theism teaches there is a personal God who created the universe. Naturalism teaches there is no divine being and that the universe is the result of time and chance. Pantheism teaches that the universe is eternal and that the divine is an impersonal force made up of all things. All three worldviews cannot be true at the same time and if one of them is true, the other two must be false.

The evidence from our study of the universe points to theism. Unfortunately, time will allow me to go over only three lines of evidence.

The first is the argument from first cause or the cosmological argument, which states if something exists, it must have either come from something else, come from nothing, or have always existed. What is the most reasonable conclusion of the three for the existence of the universe? Scientists confirm that the universe has a beginning. Many call this the "big bang." Since the universe assuredly has a beginning, the worldview of pantheism bears the burden of proof. Second, to say the universe comes from nothing goes against responsible scientific inquiry and human logic. For example, any invention in human history is not brought about from nothing. It comes from materials and ingenuity that existed before its inception. Therefore, the naturalist worldview has no logical ground to stand on. The best conclusion is that the universe is the result of a cause greater than itself. That cause is God.

Second, we have the proof of design or the teleological argument. Complexity and design point to a designer. For example, although all the parts of a watch are found on the earth, no one would assume it evolved as the result of natural, unguided actions of chance. Why would we conclude otherwise when we look at the human brain or the human anatomy, which is much more complex? The more we discover about the universe and nature, the more we realize how unlikely it is that this could have all happened by accident. Therefore, the burden of proof is on the worldviews of naturalism and pantheism, which hold to a position of evolution.

Finally we have the moral argument. All people have a sense of right and wrong. In every culture, adultery, murder, and stealing are wrong. Where does that universal sense of right and wrong come from? A moral law code requires a moral Lawgiver who is personal and reflects the moral law in His character. Since we are made in God's image, we reflect His moral law. C.S. Lewis stated, "As an atheist my argument against God was that the universe seemed so cruel and unjust. But how had I got this idea of just and unjust? A man does not call a line crooked unless he has some idea of a straight line. What was I comparing this universe with when I called it unjust?"{1} Naturalists and pantheists have difficulty accounting for the human conscience.

For these reasons, theism is the only possible worldview that can remain true to scientific and philosophical scrutiny.{2}
