Artificial intelligence is no longer simply changing how we work, communicate, or fight wars. The world’s leading technology powers are now pursuing something far more ambitious: merging AI directly with the human brain.

That future moved a step closer this month. China approved its first commercially available brain-computer interface, known as NEO, for certain patients suffering from paralysis. Meanwhile, in the United States, Neuralink has demonstrated implanted devices that enable paralyzed patients to control computers through thought alone. These are genuine medical achievements. Helping restore movement and communication to those who have lost them reflects God’s common grace at work through scientific discovery and human compassion.

But Christians should ask a question that receives far less attention: What happens when technologies designed to heal the broken begin to redefine the healthy?

Over the past two years, while researching and writing “AI for Mankind’s Future,” “The New AI Cold War,” and my forthcoming book, “The Final Algorithm,” I became convinced that artificial intelligence itself is not the greatest issue confronting the church. AI is a tool. Like every powerful technology before it, it can be used for tremendous good or tremendous evil.

The greater issue is the philosophy riding on AI’s shoulders.

That philosophy is called transhumanism.

Most Christians have never heard the term, yet they are already living in a culture shaped by its assumptions.

Transhumanism holds that humanity should deliberately transcend its biological limitations through technology. Its advocates envision artificial intelligence, brain-computer interfaces, robotics, genetic engineering, and other emerging tools as instruments not merely of healing but of directing human evolution itself. The end goal, for many, is what they openly call a “posthuman” future.

Artificial intelligence is the indispensable engine making those goals conceivable.

A brain implant without AI is an electronic sensor. Feed those same impulses through AI and they become commands — controlling computers, generating speech, assisting memory, perhaps one day augmenting cognition itself. Artificial intelligence is not merely part of this movement. It is the operating system on which transhumanism intends to run.

Christians should not confuse this discussion with opposition to medicine. Throughout history believers have celebrated advances that restore what disease and injury take away. Artificial hips, pacemakers, cochlear implants, prosthetic limbs, organ transplants, and now brain-computer interfaces helping paralysis patients recover communication all fit within medicine’s long tradition of compassionate care.

Restoration reflects compassion. Enhancement introduces an entirely different moral question.

Scripture teaches that human dignity does not depend upon intelligence, strength, longevity, or productivity. King David marveled that although mankind appears small against the vastness of creation, the Lord nevertheless “crowned him with glory and honor” (Psalm 8:5, ESV). Human worth comes from the Creator — not from technological upgrades.

That is where Christianity and transhumanism diverge.

The Christian faith teaches that humanity’s deepest problem is not inadequate intelligence or biological limitation. Our deepest problem is sin. The gospel answers that problem through redemption in Jesus Christ.

Transhumanism tells a different story. It treats biology as humanity’s fundamental limitation and technology as humanity’s path to salvation.

Christianity proclaims creation, fall, redemption, resurrection, and eternal life through Christ. Transhumanism promises enhancement, optimization, radical longevity, and, for some advocates, even digital immortality. Those are not simply competing technologies. They are competing accounts of human destiny.

Perhaps the most influential voice behind that competing account is futurist Ray Kurzweil, now a principal researcher at Google. In “The Singularity Is Nearer,” Kurzweil argues that human and artificial intelligence will merge, predicting that people will become “a combination of our natural intelligence and our cybernetic intelligence.” His goal is the expansion of human capability a millionfold by 2045 through intimate integration with machines.

Oxford philosopher Nick Bostrom, whose work has shaped governments and technology leaders alike, has argued that human enhancement should be pursued responsibly. These men deserve to be taken seriously. Their assumptions already flow through Silicon Valley, university research centers, and the national technology strategies of every major power.

The ancient temptation has never really changed. Ecclesiastes 7:29 observes, “God made man upright, but they have sought out many schemes.” Today’s schemes are infinitely more sophisticated than those of earlier generations. The goal, however, remains the same: improving upon what God has already declared good.

Christians, therefore, face neither a technological crisis nor a scientific crisis. We face a discipleship challenge.

Will we define humanity according to Silicon Valley or according to Scripture?

James reminds believers that “the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits” (James 3:17, ESV). Artificial intelligence may process astonishing quantities of information, but wisdom remains God’s gift — not an algorithm’s achievement.

Paul’s command to “take every thought captive to obey Christ” (2 Corinthians 10:5, ESV) carries fresh weight in an age when millions reach for a chatbot before opening their Bibles. AI can become an extraordinary research assistant. It must never become our spiritual authority.

So, what should Christians do?

First, recover a clear biblical understanding of humanity. We are not biological accidents awaiting technological improvement. We are men and women created in God’s image for His glory.

Second, welcome technologies that genuinely heal suffering while exercising great care whenever enhancement begins to displace restoration.

Third, teach our children. Most young believers have never encountered the word “transhumanism,” yet they are absorbing many of its assumptions through entertainment, social media, and the classroom.

Fourth, follow Paul’s counsel: “Test everything; hold fast what is good” (1 Thessalonians 5:21, ESV). Christians should neither reflexively reject every innovation nor uncritically embrace it. Discernment — not fear or naïveté — must guide us.

Finally, remember where our hope truly rests.

Artificial intelligence may someday help restore damaged bodies. Technology may extend human capabilities in ways we cannot yet predict. But no algorithm can redeem a soul. No brain chip can erase sin. No machine can confer eternal life.

“Our citizenship is in heaven,” Paul reminds us, “and from it we await a Savior, the Lord Jesus Christ, who will transform our lowly body to be like his glorious body” (Philippians 3:20–21, ESV).

That is Christianity’s answer to transhumanism.

Our future is not found in becoming something beyond human. It is found in becoming fully restored through the One who created us, redeemed us, and one day will make all things new.

Christians should certainly ask what machines will eventually be capable of doing.

The more important question is whether we will remain faithful to what God created humanity to be.
