I. First reason: The First Cause. (Psalm 90:2)
Psalm 90:2 says, “Before the mountains were born, before You gave birth to the earth and the world, from eternity to eternity, You are God.” So God has always existed, but the universe has not always existed. The universe had a beginning, when God created it out of nothing.
But why should we believe this? We have clear evidence that the universe has not always existed. Instead, it began to exist. If it began to exist, what started it? What was the first cause? The answer is God!
Someone might ask, “How do we know the universe has not always existed? How do we know that it started sometime in the past?” We know this from logic, and science also confirms it.
Think about it. It is logically impossible for the past to go into infinity. It is impossible to count down from infinity to one. There is always an infinite distance to travel, so we never arrive. In the same way, if the past went on into infinity, we could never arrive at the present. But here we are! So there must have been a beginning. (Douglas Groothuis, Christian Apologetics, p. 219-223)
Science has also given us reason to believe in a first cause. In 1929, astronomer Edward Hubble discovered that a dozen galaxies near earth were moving away from us at high speeds. Scientists today agree that the universe is expanding, because it had a beginning, which they often call the “Big Bang.” Scientists don’t know what caused the big bang, they just know it happened. But as Christians, we know that caused the Big Bang. God spoke, and bang! It happened.
The Big Bang Theory is not the only scientific reason to believe in a first cause. There is also the second law of thermodynamics. This scientific law states that the energy in the universe is slowly but surely being used up. Like a fire that eventually burns out, all the energy in the universe is eventually going to disappear. Now here’s where it gets interesting. If the universe existed for eternity in the past, then it would have already used up all the energy by now. But here we are, with energy still available to use. So the universe is not eternal; it had a beginning in the past. What other way is there to explain this beginning, except that an all-powerful, supernatural person was the first cause? (Groothuis, p. 224-226)
The only answer atheists can have to this, is to argue that the universe was caused by nothing but a pure accidental explosion. Not only does it take more faith to believe the beautiful complexity of the universe had no cause, but such belief would also mean that everything in life is meaningless, and has no cause or reason. So would you prefer to believe that an all-powerful Creator spoke the word and brought the universe into being with a purpose, or would you prefer to believe that everything began from no cause, and life has no meaning? The choice is yours, but thank God we have a better choice than to live a meaningless life that began by nothing and has no purpose. Instead, it makes far more sense to believe that there was a First Cause, a supernatural Being, who brought the universe into existence, and that our lives do have purpose and meaning.
II. Second reason: Self-Consciousness. (Genesis 2:9; Romans 7:22)
Those who believe in Darwinian evolution, think that the human being is a mere biological collection of atoms that assembled by chance over a long period of time.
The Bible, on the other hand, says that God formed mankind from the earth, and we became a “living being.” (Genesis 2:9). Romans 7:22 talks about understanding something “in my inner self.” Whether or not you believe the Bible, we all know that we have an inner self, a self-consciousness. As the philosopher Rene Descartes said, “I think, therefore I am.” I have an awareness of my own self; I have something within myself that makes me to be me.
But where in the human body is my consciousness located? Where is my self-awareness? No scientist has located it. Nobody can tell you that in this part of the brain, or any other place on the human body, is the location of self-consciousness. Nobody can tell you where it is, yet we know we have it.
And if I am only a biological collection of chemicals, then how do we explain the human appreciation for beauty, music, poetry and art, and how do you explain love?
If you are an atheist, there is no explanation for it. But if you believe in God, the answer is simple: God put it there.
III. Third reason: Religious Experience (John 9:25)
The man born blind who was healed by Jesus could testify to a changed life, and nobody could dispute his experience. In John 9:25 we read, “He [the blind man] replied, ‘Whether he [Jesus] is a sinner or not, I don’t know. One thing I do know. I was blind but now I see!'”
In Isaiah 6:1-5, Isaiah had a face-to-face encounter with the Lord in the temple; in Acts 9:1-9, Saul met the Lord on the road to Damascus and had a life-changing conversion experience.
This series of blog posts was originally presented as a series of sermons at the church I was serving in near Savannah, Georgia. When I presented the message, a student at Armstrong Atlantic State University, came forward at the end of the early worship service to publicly profess her faith, and at the second morning service, she gave her testimony to the congregation. She told how she did not believe in the existence of God, but she began to seek God. She heard all of the same arguments for the existence of God that we have talked about last week and this week, but she was still undecided about whether she believed. Then she decided to go with the Baptist Collegiate Ministry at Armstrong Atlantic State University on a mission trip to Haiti. That week, she prayed, and said, “God, if you are there, will you reveal Yourself to me.” Later in the week, she was walking through a voodoo area of Haiti, where all of the statues had been destroyed by the earthquake, and she looked up and saw a statue of Jesus on the cross. Her friend had been encouraging her to have faith in God, and right then she looked up and saw the statue. She decided that if she turned away then, she would never believe. That experience finally brought her to belief in God and faith in Jesus Christ.
The religious experience of millions of people is a powerful evidence for God. People can deny the existence of God, but they cannot deny the fact that millions of people of every time, language and culture have believed in God and claimed to have an experience with God. When the white men first came to the New World, they found Native Americans who had never had contact with Western society, yet they believed in a Great Spirit.
Atheists sometimes claim that people who believe in God are ignorant, or even neurotic. But they have a more difficult time making this claim when confronted with the fact that so many great leaders like George Washington and Abraham Lincoln believed in God, great musicians like Ludwig von Beethoven and Johann Sebastian Bach believed in God, great artists like Leonardo da Vinci believed in God and great scientists like Werner Van Braun believed in God. My late uncle, Dr. R.A. Clinton, Jr., was a rocket scientist who worked alongside Van Braun in building a satellite at the space center in Huntsville, Alabama. My uncle later became the leading American expert on Russian missile technology. Yet brilliant as he was, Uncle R.A. was also a believer, who taught Sunday School at First Baptist Church of Huntsville for over 25 years.
Atheists often claim that much harm and cruelty has been done in the name of God. However, atheists must also face the fact that millions of people were massacred by atheist dictators like Joseph Stalin and Mao-tse Tung. Atheists are correct that people with distorted views of God have done great harm, whether they were misguided people who claimed to follow Christ, as in the Crusades, or the brutal terrorists of ISIS. This points to the fact that it is not enough to believe in the existence of God; one needs to know the personal God who has revealed Himself to us in Jesus Christ, and truly obey Him. True followers of Christ have fed millions of hungry and in the name of God millions of sick have been nursed to health. After Hurricane Katrina, there were no atheist relief organizations to help, but thousands of churches and Christian organizations came to help. The life-changing experience of the God of the Bible, Jesus Christ, is the greatest reason I know to believe in God. How about you? Do you believe?
