Does God Exist? Five Reasons to Believe

Does God Exist? Five Reasons to Believe

Introduction
The question of God's existence has engaged philosophers, theologians, and scientists for millennia. Rather than relying solely on faith, Scripture invites us to examine the evidence—both in creation and within ourselves. The following five arguments present compelling reasons to believe in God, drawn from biblical truth and observable reality. These points are designed to challenge skepticism and encourage genuine inquiry into whether God exists.

 
Argument 1: The Universe Had a Beginning

 Everything that begins has a cause. What, then, caused the universe?

Modern cosmology confirms that our universe had a definite beginning. The Big Bang theory, supported by contemporary physics, demonstrates that the universe emerged from an initial singular state. However, science alone cannot answer what caused this beginning—what set creation in motion.

Genesis 1:1 states: "In the beginning God created the heavens and the earth." This is not a random beginning, but one initiated by divine purpose.

Consider the logical implications: the universe cannot have created itself, as it did not yet exist. It cannot be eternally self-existent, as scientific evidence shows it had a starting point. Therefore, any cause of the universe must possess characteristics beyond the physical:

Transcendent of time – existing outside temporal constraints
Immaterial – not subject to physical laws
Infinitely powerful – capable of creating all matter and energy
Personal – possessing will and intentionality to choose creation
These attributes align precisely with the biblical concept of God.

Romans 1:20 declares: "For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse."

The evidence of God's existence surrounds us continually in the physical cosmos.

 
Argument 2: The Fine-Tuning of the Universe

Opening Question: Change gravity by 0.00000000001%, and you would not exist. Is this coincidence?

Scientists have discovered that our universe displays extraordinary fine-tuning—a precision so exact that even minor variations would render life impossible.

Consider specific examples:

Gravitational Force: A marginally stronger gravitational constant would cause stars to burn out within a year. A marginally weaker one would prevent star formation entirely.
Strong Nuclear Force: If this fundamental force varied by merely 2%, atomic nuclei could not form, and chemistry would be impossible.
Cosmological Constant: This value must be precise to 1 part in 10^120—equivalent to targeting a single grain of sand across the entire observable universe.
Even secular physicists acknowledge this as "suspicious" or "spooky." Some have proposed the existence of infinite alternate universes merely to avoid the obvious inference: intelligent design.

Psalm 19:1 proclaims: "The heavens declare the glory of God; the skies proclaim the work of his hands."

The mathematical precision of creation does not whisper design—it loudly proclaims it. The probability of such fine-tuning occurring by chance approaches zero, whereas the probability of a Designer becomes not only plausible but necessary.

 
Argument 3: The Problem of Objective Morality

If God does not exist, why is stealing wrong? More broadly, why is anything morally wrong?

One of the most compelling arguments for God's existence emerges from the reality of objective morality. If the universe is purely material—if humans are merely sophisticated organisms—then morality becomes subjective opinion rather than objective truth.

Consider this challenge: You believe murder is wrong. Most people agree. But on what objective basis do you assert this? Without appeal to a transcendent standard, morality reduces to personal preference. One person's conviction differs from another's with no rational means of arbitration.

Yet humans universally recognize certain acts as genuinely wrong—not merely distasteful, but wrong. This universal moral intuition across cultures and centuries suggests something beyond evolutionary survival instinct.

Romans 2:15 explains: "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."

Every human civilization has prohibited murder, theft, and betrayal. This consistency is not coincidental; it reflects a moral law inscribed on human nature itself—evidence of a Moral Lawgiver.

Your own actions confirm this truth. Every time you declare something "unfair" or "unjust," you implicitly appeal to an objective moral standard. You live as though morality is real, even if your philosophy denies it.

 
Argument 4: Jesus Christ—The Ultimate Evidence

One man fulfilled over 400 specific prophecies written centuries before his birth. What are the odds of this occurring by chance?

The life, death, and resurrection of Jesus Christ constitute the most compelling evidence for God's existence. Jesus was not merely a moral teacher; the biblical record and historical evidence point to his identity as God incarnate.

Prophecy Fulfillment:

The Old Testament contains hundreds of prophecies concerning the Messiah, written centuries before Jesus' birth. Consider the precision:

Micah 5:2 foretold: "But you, Bethlehem Ephrathah, though you are small among the clans of Judah, out of you will come for me one who will be ruler over Israel, whose origins are from of old, from ancient times."

Isaiah 7:14 prophesied: "Therefore the Lord himself will give you a sign: The virgin will conceive and give birth to a son, and will call him Immanuel."

Psalm 22—written approximately 1,000 years before crucifixion—describes the precise manner of Jesus' execution with remarkable accuracy, long before crucifixion was even a Roman practice.

Psalm 16:10 promised: "because you will not abandon me to the realm of the dead, nor will you let your faithful one see decay."

The mathematical probability of any single individual fulfilling just eight of the major Messianic prophecies is calculated at 1 in 100 quadrillion. Jesus fulfilled over 400.

The Resurrection:

Beyond prophecy, the resurrection of Jesus presents the most historically documented miracle. Over 500 witnesses testified to encountering the risen Christ. The disciples, initially cowering in fear, became bold proclaimers willing to suffer torture and death for their testimony.

People do not die for lies they know to be false. The disciples' willingness to be executed for their witness—particularly given their initial skepticism—argues powerfully for the reality of the resurrection.

John 1:1 and 1:14 declare: "In the beginning was the Word, and the Word was with God, and the Word was God... The Word became flesh and made his dwelling among us."

Jesus is God's ultimate evidence presented in human form. If the resurrection is true, all of existence changes fundamentally.

 
Argument 5: The Testimony of Human Conscience

 Why do you feel guilt even when no one is watching?

The human conscience provides remarkable evidence for God's existence—an inner voice that testifies to moral reality independent of external reward or punishment.

Evolution, as a mechanism, selects for traits promoting survival and reproduction. It would logically reward self-interest and the concealment of wrongdoing when detection is unlikely. Yet humans consistently experience:

Guilt over hidden actions that harm no one materially
Admiration for those who sacrifice themselves for strangers
Conviction of wrongdoing even when personal benefit is assured
An inescapable sense that certain acts are genuinely wrong, not merely inadvisable
This phenomenon transcends evolutionary explanation. It points to something beyond material reality—the imprint of the divine upon human nature.

Romans 1:19-20 states: "what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse."

Ecclesiastes 3:11 adds: "He has made everything beautiful in its time. He has also set eternity in the human heart; yet no one can fathom what God has done from beginning to end."

Your sense of justice, your capacity for love, your yearning for meaning—these transcendent qualities point beyond material existence to their source: God. Even the atheist philosopher Thomas Nagel has conceded, "I want atheism to be true, but it doesn't fit the evidence."

You cannot ultimately suppress the truth inscribed within you. God has written eternity upon your heart.

 
Conclusion
These five arguments—the universe's beginning, its extraordinary fine-tuning, objective morality, the resurrection of Christ, and the testimony of conscience—converge to present compelling evidence for God's existence. This is not blind faith, but reasoned belief grounded in observable reality and historical testimony.
