Top Ten Questions People Ask About the Christian Faith:
How Do You Know There is a God?

At some point in time, you have questioned whether or not there is a God. Even the most devout Christians have experienced moments of doubt.

The question of the existence of God is actually the key difference when it comes to calling oneself an atheist, an agnostic, or a believer.

An atheist does not believe in God or any deity.

An agnostic doesn’t know if there is a God.

A believer does believe in God and His hand in the creation of the universe and our individual lives.

In this blog series, “Top Ten Questions People Ask About the Christian Faith,” we plan to answer some of the most popular questions people have about the Christian faith.

Therefore, it makes sense to start at the very beginning – how do you know there is a God?

Let’s discuss it so you may be prepared to answer this question yourself one day.

Our Understanding of Right and Wrong

A key argument for the existence of God is a moral one.

The basis of the theory of morality holds that every person innately knows the difference between right and wrong and good and evil.

It is hard-wired inside us, and it explains why we fight passionately for what we believe is right and true.

The question then becomes, where did this come from?

Why would we feel this way if there was no God to hold us accountable for our actions?

Why would we care about morality at all?

“Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law. They show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts sometimes accusing them and at other times even defending them.”
– Romans 2:14-15

Our Very Existence

Another key argument for the existence of God comes down to our very existence.

This is called a cosmological argument. defines it this way: “an argument for the existence of God, asserting that the contingency of each entity, and of the universe composed wholly of such entities, demands the admission of an adequate external cause, which is God.”

It is a fancy way to say we wouldn’t exist if God didn’t exist first.

Think of it this way. A garden needs a gardener. A painting must have a painter. A building must have a builder. A creation must have a creator.

In other words, how did we get here if not for God? How was this amazing world created without a Creator?

“In the beginning God created the heavens and the earth.”
– Genesis 1:1

“So God created mankind in his own image, in the image of God he created them; male and female he created them.”
– Genesis 1:27

Our Intricate World

Some use the argument of the intricacies of our world to argue the existence of God.

This is known as a teleological argument, which is essentially the theory of design.

For example, have you ever looked at a snowflake up close?

The intricate details of a snowflake are stunningly beautiful, making each snowflake unique.

“To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I confess, absurd in the highest degree.”
-- Charles Darwin

Likewise, the details put into the creation of the earth and human beings are mind-blowing.

For instance, how our sun and moon control the ocean tides or the amazing way babies are formed inside their mother’s wombs over 40 weeks.

These types of details insist a Creator created us with an intricate plan and an eye for detailed design.

“For you created my inmost being; you knit me together in my mother’s womb. I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well.”
– Psalm 139:13-14

Our History

Possibly the best argument for the existence of God is your personal story.

Throughout Scripture, people believed in the existence of God by remembering their history and reminding themselves of what God had done for them.

The Israelites saw God free them from slavery, and the generations following looked on this part of their history as proof of God’s existence.

Similarly, the disciples saw Jesus die and rsurrect from the dead as proof of God’s existence, and the message of Jesus is what led to the formation of the church as we know it today.

What has God done in your life that proves He is real? How does your history prove God’s existence?

“A heathen philosopher once asked a Christian, ‘Where is God?’ The Christian answered, ‘Let me first ask you, Where is He not?’”
-- Aaron Arrowsmith

If Anyone Lacks Wisdom…

The journey to belief in God is different for each of us.

However, Scripture tells us if we lack wisdom, we can ask God, and He will give it (James 1:5).

  • Pray for God to reveal Himself to you and those in your life who do not believe.
  • Spend time reading the Bible.

When Bible stories begin to come to life for you, it is much harder to deny the existence of God.

  • Finally, do your homework.

Some people, like The Hole in Our Gospel author and World Vision President Richard Stearns, only became believers after doing their own research.

There are several outstanding, well-researched books that tackle this difficult topic.

Here are a few to get you started:

“I believe in Christianity as I believe that the Sun has risen, not only because I see it, but because by it I see everything else.”
- C. S. Lewis
