Does God exist, and how can we know?
Romans 1:18-20
18 The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness,
19 since what may be known about God is plain to them, because God has made it plain to them.
20 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.
New International Version (NIV)
The answer
Yes—God exists, and He can be known because He has revealed Himself. His existence is not a human guess: God displays His power and deity in creation, has spoken through the prophets, and has revealed Himself supremely through His Son.
Creation bears witness to God
Romans 1:19 says that what is known about God is evident because “God revealed it to them.” Romans 1:20 explains that, since the world’s creation, God’s invisible qualities “are clearly seen, being perceived through the things that are made, even his everlasting power and divinity.” The created world therefore testifies to an eternal, powerful, divine Creator.
This revelation leaves humanity “without excuse,” as Romans 1:20 concludes. No one can rightly claim that God has provided no testimony to Himself.
God has spoken and sent His Son
Creation reveals God’s power and deity; God’s spoken revelation makes Him known more fully. Hebrews 1:1-2 teaches that God spoke through the prophets and has now spoken through His Son, through whom He also made the worlds.
Hebrews 1:3 describes the Son as “the radiance of his glory, the very image of his substance.” He upholds all things and has purified sinners from their sins. God is therefore known not merely by reasoning from the world, but through His own Word and through the person and saving work of Jesus Christ, His Son.
Unbelief can involve resisting the truth
Romans 1:18 says that people can “suppress the truth in unrighteousness.” Unbelief is therefore not always simply a lack of evidence; it can involve moral and spiritual resistance to God. This does not make every question insincere, but it warns against using questions to avoid what God has already made known.
Hebrews 11:6 gives the right response: “he who comes to God must believe that he exists, and that he is a rewarder of those who seek him.” Faith is not pretending that God exists without grounds. It is trusting the God who has revealed Himself and genuinely seeking Him.
Answered from Scripture · reviewed November 11, 2026
Scripture never pauses to argue the existence of God as an open hypothesis; it proclaims Him as the living Creator who has made Himself undeniably known. From the grandeur of the cosmos to the testimony of human conscience and the supreme revelation of Jesus Christ, God has left no one with an excuse for denial.
General Revelation
Creation leaves every human being without excuse
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.
Romans 1:20 (NIV)
It shows that God's eternal power and divine nature are clearly seen through what He made, rendering every unbeliever entirely without excuse.
The question of God's reality is never treated in Scripture as an unresolved dilemma, because God has made His eternal power and divine nature plain to every living soul through the world He constructed (Romans 1:20). According to Romans 1:18, unrighteous humanity engages in active suppression of truth rather than passive ignorance, even though God has openly manifested that truth within them (Romans 1:19). The universe speaks with an unbroken voice: David declares in Psalms 19:1 that the heavens constantly recount the glory of God, an audible testament poured out across day and night without cessation (Psalms 19:2). Looking upon the vastness of the moon and stars, man is arrested by the majesty of the One who ordained them (Psalms 8:3-4), while the sheer variety and balance of the natural order attest to divine wisdom (Psalms 104:24). Even the animal kingdom bears witness, as Job reminds his companions that beasts, birds, and fish declare the sustaining hand of the Lord (Job 12:7-10). When God breaks His silence to Job, He points to the very laying of cosmic foundations and the singing of morning stars as proof of unmatched authority (Job 38:4-7). Isaiah similarly directs weary eyes upward to the celestial host, noting that not one star is missing because God calls each by name (Isaiah 40:26). This disclosure is neither remote nor abstract. Speaking in Lystra, Paul reminded pagan listeners that God provided a continual witness in fruitful seasons, rain, and daily gladness (Acts 14:17). Standing before Athenian philosophers, he insisted that the God who made heaven and earth (Acts 17:24) placed nations in their appointed seasons precisely so they would reach out and find Him, knowing He is never far away (Acts 17:27), for in Him we live, move, and have our being (Acts 17:28). Thus, humanity is left entirely without defense when it fails to honor Him (Romans 1:21).

Heart And Conscience
Denial is a moral rebellion rather than ignorance
The fool says in his heart, “There is no God.” They are corrupt, their deeds are vile; there is no one who does good.
Psalms 14:1 (NIV)
It unmasks atheism not as an intellectual defect, but as a deliberate corruption of the moral heart.
Scripture locates the denial of God not in intellectual deficiency, but in a fractured moral posture: the fool says in his heart there is no God because his affections are deeply corrupt (Psalms 14:1; Psalms 53:1). Atheism and agnosticism are fundamentally moral refusals rather than evidential shortages. God has woven the architecture of His moral law directly into the human soul, so that even those who never possessed the written Scriptures demonstrate the law's demands by nature (Romans 2:14). Their conscience stands as a relentless inward witness, alternately accusing or defending them (Romans 2:15). Deep within, mankind perceives the righteous decree of God that evil merits holy judgment, yet sinners not only commit these deeds but celebrate those who join them (Romans 1:32). This state of alienation is driven by darkened understanding that stems directly from hardness of heart (Ephesians 4:18). Man cannot escape this inward tug because the Creator has deliberately placed eternity into the human heart (Ecclesiastes 3:11), planting an awareness that life extends far beyond material boundaries. The human spirit functions as the lamp of the Lord, exposing every hidden thought and motive (Proverbs 20:27). While fallen man deceitfully hides from his own depravity, the Lord searches the heart and tests the mind (Jeremiah 17:9-10), demonstrating His existence and holy rule through every pang of genuine conscience.

Special Revelation
God has made Himself known in Christ and Scripture
In the past God spoke to our ancestors through the prophets at many times and in various ways,
Hebrews 1:1 (NIV)
It sets Christ forward as God's decisive, supreme self-revelation who culminates everything spoken through the prophets.
While creation and conscience prove God's reality, His ultimate and intimate self-disclosure arrives in the person of Jesus Christ, who is the radiance of God's glory and the exact imprint of His divine nature (Hebrews 1:3). For centuries the Lord spoke through prophets in diverse ways (Hebrews 1:1), but in these final days He has spoken definitively through His Son, whom He appointed heir of all things (Hebrews 1:2). Jesus is the eternal Word who was in the beginning with God and was God (John 1:1). No human has seen God's unmediated essence at any time, but the only begotten Son, dwelling in the bosom of the Father, has made Him fully known (John 1:18). When Philip asked to see the Father, Jesus responded with breathtaking clarity: whoever has seen Him has seen the Father (John 14:9). This revelation is preserved without error in holy Scripture, breathed out by God to instruct, correct, and train believers in righteousness (2 Timothy 3:16). Genuine faith recognizes that anyone drawing near to God must believe that He exists and rewards those who seek Him (Hebrews 11:6), just as God named Himself the eternal 'I AM' before Moses (Exodus 3:14). Christ's historic miracles and resurrection were purposefully recorded so that we may believe He is the Son of God and find life in His name (John 20:30-31), founded not upon cunning myths, but on the recorded testimonies of eyewitnesses who beheld His majesty (2 Peter 1:16-18; 1 John 5:20).

Prophetic Proof
Fulfilled Prophecy Proves the Living God
Remember the former things, those of long ago; I am God, and there is no other; I am God, and there is none like me. I make known the end from the beginning, from ancient times, what is still to come. I say, ‘My purpose will stand, and I will do all that I please.’
Isaiah 46:9-10 (NIV)
God explicitly stakes the proof of His unique, unmatched deity on His sovereign ability to declare the end from the beginning.
To settle the question of who is the true and living God, the Lord challenges all rival worldviews in the courtroom of history: He alone declares the end from the beginning and brings ancient prophecies to literal fulfillment (Isaiah 46:9-10). In the prophetic indictments of Isaiah, God confronts idols to present their best defense by predicting future events or explaining the meaning of the past (Isaiah 41:21-24). Because pagan idols and human philosophies cannot anticipate the future, their claims are utter vanity. In contrast, the Lord announces new things long before they spring forth into public sight (Isaiah 42:9). He stands alone as the First and the Last, outside of whom there is no Rock, calling on anyone who dares to equal Him to proclaim upcoming events as He has consistently done (Isaiah 44:6-8). This same signature of absolute deity appears throughout the earthly ministry of Jesus Christ. He explicitly foretold events—including His betrayal, suffering, and resurrection—before they happened, explaining to His disciples that when it occurs, they may know and believe that 'I am He' (John 13:19). The precision of biblical prophecy, unfolding across millennia and centering upon the redemption accomplished in Christ, provides undeniable historic proof that God is real, sovereign, and faithful to His word.
