Existence of God

Some people claim that evolution has defeated the argument for God’s existence from the design found in life, but has it? Evolution is the idea that all of life can be traced back to a common ancestor and that natural selection of random mutations can explain all the diversity in life. We know that natural selection is simply a scientific fact, but how powerful is it? Can natural selection produce new types of organisms? One scientist, Michael Behe, has argued that natural selection is not powerful enough to produce new species. Based on the evidence from studying fruit flies, malaria interacting with sickle-cell anemia, and HIV, Behe says that there seems to be a limit to what the evolutionary process can produce that falls short of new species. If this is true, then it indicates that evolution, on a large scale, is false. If evolution is false, then certainly it can’t prove that there is no God. However, even if evolution is true, it still doesn’t prove that there is no God. It might weaken the design-of-life argument somewhat, but evolution still can’t explain the origin of life in the first place. Plus, there are many other good arguments for God’s existence that aren’t related to evolution at all. The existence of God and evolution are not mutually exclusive beliefs.

The design argument for God’s existence, also called the “teleological argument” or the “fine-tuning argument,” says that God exists because the universe, earth, and life all look like they have been designed. This type of argument has been around for thousands of years, being formulated by figures such as Socrates, Plato, and even Hindu thinker Adi Sankara. Through empirical observation, we can see that every design has a designer. We’ve never observed design coming from any other source than from an intelligent mind. How do we detect design? When something is both complex (it has multiple parts) and specified (the parts are not randomly arranged), it can be said to be designed. One way we notice design in the universe is by the fine tuning of its physical constants. We also notice design in the way that the earth is very specifically situated in our galaxy and solar system to allow life to exist. Finally, we notice design in the way life itself is put together and in the information it contains in its DNA. All of this evidence of design points to the existence of a designer, an intelligent supreme being like God.

The first-cause argument for God’s existence, often called the “kalam cosmological argument,” says that God exists because the universe had a beginning. If the universe had a beginning, then the universe needs a first cause, and that cause is likely God. In fact, there have been many first-cause arguments made by philosophers in different cultures, such as Aristotle’s unmoved mover. Today, it is well established that everything that beings to exist has a cause; things don’t just pop into existence out of nothing. In addition, based on the evidence from many scientific discoveries, scientists almost unanimously agree that the universe had a beginning. This is based on Einstein’s general theory of relativity, Hubble’s discovery of the red shift through his telescope, cosmic background radiation, and other phenomena. Therefore, since everything that begins to exist has a cause, and the universe began to exist, then the universe must itself have a cause. But what is this cause? From the first-cause argument, we can infer that this cause must be spaceless, timeless, immaterial, incredibly powerful, and intelligent – much like how God is described.

In the last few decades scientists have discovered numerous astonishing facts about our universe that seem to indicate it has been precisely fine-tuned for life. As engineers who design our spaceships to sustain human lives in space can attest, life can only exist if numerous factors are set to precise specifications. Similarly, our universe seems to have been finely tuned for intelligent life to exist and thrive. The fact that these laws of physics are set just so has led many to conclude that our universe was designed by a supreme being with an intelligent mind.

Everyone seems to have an idea of right and wrong. We know that being loving and forgiving are good things to do. We know that it is wrong to murder or to rape. We all know about the existence of moral rules, such as "Thou shalt not steal" and "Love your neighbor as yourself." In philosophy, the study of these moral rules, of right and wrong, good and bad, is called ethics. So, what makes something good or bad? We might know what things are good and bad, but why is something good or bad? Who's to say that loving someone is good but hating them is bad? Where do right and wrong come from? In philosophy, this area of study is known as "metaethics," and in this series, Adam explores both theistic and atheistic theories of what makes something morally good or bad. Is God the foundation of morality, or is God not needed to explain the source of moral values and duties? What does it even mean to say that God is the "foundation" of morality?

Both Christians and Muslims affirm the following argument:

However, which understanding of God, the Christian’s or the Muslim’s, is a better explanation for objective morality? In this paper I argue that Christianity’s trinitarian God is a better explanation for objective morality than Islam’s God. As part of this argument, I propose a Trinitarian Metaethical Theory (TMT) which maintains that the ultimate ground of morality is God’s trinitarian nature.

Who was Jesus? Christians believe that Jesus was God incarnate, in other words, God in human form. But how can we really know who Jesus was? Did Jesus himself claim to be God? The Bible attempts to prove Jesus’ divinity by recording many miracles that He performed, but are miracles even possible? All the stories about Jesus are written in the first four books of the New Testament, but how do we know that what they say about Jesus is true? Did those things, even the miracles, actually happen? Christians stake their faith on the greatest miracle of all, Jesus’ resurrection from the dead. But what evidence is there for this? Journey with Adam through this nine-part series where he explores the historical accounts of Jesus found in the New Testament and how we as Christians can trust that Jesus is really God.

God’s existence is a topic that undergirds all of Christian apologetics. If God does not exist, then Christianity cannot be true. However, God does exist, and there is much evidence of that fact in the world around us. In this lecture, Adam explains “The Big 3” arguments commonly put forward for God’s existence: the cosmological argument or the argument from the beginning of the universe, the teleological argument or the argument from the design in the universe, and the moral argument or the argument for a moral lawgiver.

Why salvage divine simplicity? Consider the Euthyphro Dilemma, often presented as a rebuttal to the moral argument for God’s existence. In Plato’s Euthyphro, Socrates asked “Is that which is holy loved by the gods because it is holy, or is it holy because it is loved by the gods?”1 The dilemma can be restated in monotheistic terms as follows: Either 1. Morality is based on God’s commands; thus, He could have arbitrarily commanded any heinous act and it would be morally right, or 2. Morality is based on necessary truths that even God cannot change; thus morality is independent of God and out of His control.2

In order to avoid both horns of the dilemma, theists have proposed that morality is dependent upon God’s nature in such a way that He could not command something that violates His moral nature.3 Robert M.

In this interview with Ratio Christi’s Truth Matters, Adam discusses the objectivity of morality and the moral argument for God. He gives an overview of Robert M. Adams’ metaethical model which posits that God is the best explanation for morality. What are some common objections to this model? Could evolution have produced morality? What is natural law and how does it relate to objective morality? Does morality come from God’s commands? Did morality change from the Old Testament to the New Testament? Why do some of God’s commandments in the Old Testament seem so odd? Watch the interview to discover the answers to these questions and more.
