The condition of mankind can be compared in some ways to an analogy developed by the late evangelist and philosopher Francis Schaeffer.1 Imagine trying to piece together
the story from a book whose pages had all been mostly ripped away, leaving only a strip of remaining type on each page. Looking at the remaining text alone, it would be
impossible to figure out the whole story. However, if we further imagine that the ripped out pieces were hidden in the attic, and you were able to find them and examine
them, then it would be possible to discern that they were indeed the missing pieces to the book in your hand, and looking at the completed pages, you could find out the
whole story. In this analogy, the book with the remaining bits of text corresponds to the facts available to all people: the external universe and human nature. The ripped out
pages represent God’s revelation to mankind—the Bible. When we compare God’s revelation to us in the Bible with the world we see around us, we find a perfect match. The
Bible, unlike any other competing claim to truth, coherently and self-consistently explains the range of evidence available to us all: the external universe and human nature.
When we compare God’s revelation to us in the Bible with the world we see around us, we find a perfect match.

The Bible uniquely explains why we see both astonishing design and tragic decay and evil. It explains the paradox of human nature: that we are simultaneously loving and evil,
caring and cruel. And unlike atheistic or polytheistic systems, the biblical worldview provides the necessary framework for the pursuit of science: a stable, predictable
cosmos governed by absolute and unchanging physical and logical laws, a habitable zone suitable for life and scientific pursuit (against all odds!), and human bodies and
minds with the innate capacity to properly observe and comprehend the universe around them. In addition, the facts of science and history available to us line up with and
provide corroboration for the claims of Scripture. Far from being an isolated, purely hypothetical solution, the biblical worldview is well-attested by many lines of evidence.
In light of this, Paul the Apostle justly proclaims that we are “without excuse” for denying God (Romans 1:20). But, as our ministry has pointed out in many places, people
generally interpret the evidence through the ‘glasses’ of their worldviews, meaning that unbelievers are often blinded to the clear and powerful evidence that exists in favor
of the Bible—they don’t see it because they don’t step outside their presuppositions.
How should we present the Gospel to those who reject the Bible?
So what, then, should we do as Christians when confronted with unbelievers who deny the Bible is true? Before proceeding, it’s important to be aware that there is no ‘magic
bullet’ in witnessing and apologetics. Ultimately, our final commitment to God is part of the internal work of the Holy Spirit in our lives and the state of the heart—not the
mind. Therefore, our job as apologists and evangelists consists of presenting the Gospel and, if necessary, removing intellectual stumbling blocks. Regardless of your skill,
there is no way to argue a person into the Kingdom of God!
With that said, however, it can be helpful to have a game plan when dealing with skeptical nonbelievers. Schaeffer took an approach he named ‘Taking the Roof Off’, which
informed Christians would do well to emulate. To truly witness to someone, we must treat them as a genuine human being. We must get to know them as an individual and
assess their worldview on its own terms. Apologetics—witnessing to skeptical nonbelievers by giving answers to their objections—if it is to be successful, must truly be a
personal interaction, and not just an academic pursuit or a chance to get in the last word. Since non-Christian worldviews inevitably break down at one point or another and
fail to explain reality, there will always be a ‘point of tension’ where the unbeliever’s worldview is at odds with the real world. It is at this critical point that the unbeliever
builds up a psychological ‘roof’ over their head to shield themselves from the reality their worldview fails to deal with. To really get through to such a person, we must ‘take
the roof off’ by showing the person the unpleasant and unsatisfactory consequences of their own belief system, and forcing them to acknowledge them head-on.2 This can
(and should) truly be an uncomfortable experience for them. Only in this way can we get down to the heart of the matter, and perhaps, with the guidance of the Holy Spirit,
shake them from their disbelief and turn them to God.
What might this look like in a day-to-day example? Imagine that you’ve just met a person and found out that they’re very interested in technology and science, and is an
atheist as a result of a commitment to a Darwinian naturalistic worldview. You might ask them, “What is the point of doing science?” Most likely you’ll get a response that
waxes poetic about the virtues of science as a means to improve the lives of people—making us happier and healthier—and leading ultimately perhaps to a new utopian age
of prosperity driven by scientific advancement. In this case we are dealing with a worldview (evolutionary naturalism) which cannot provide a basis for meaning or purpose
in life, or for the value of human life.
This unbeliever’s ‘roof’ is their irrational blind leap of faith to believe that science can solve all the problems of death and suffering in the world, and that human life has
intrinsic value apart from God. Removing their roof, exposing them to the true ugliness of the Darwinian worldview, will show them their need for God and a Savior, and
prepare them for receiving the Gospel. This is known as pre-evangelism. To do this, we need to gently point out the fact that, if Darwin was right about life being a product of
blind natural processes, then human life has no intrinsic value. In the Darwinian scheme, humans are nothing more than higher apes—in other words, we are not special.
We are just animals which happen to have evolved differently from other animals (we cannot even say ‘better’ or ‘higher’, since that would imply an objective standard
which cannot be justified). In fact, life itself is nothing special, but just represents a different configuration of the same ‘stuff’ that makes up the rest of the universe.
The only real difference between a human being and a coconut—or a rock—would be that humans have a different configuration of atoms. Therefore, there’s no point in
saying that we should do science to improve human life, because human life is not valuable in the first place! Since the intrinsic value of human life is self-evidently obvious
to all (except perhaps sociopaths), making this point should strike a chord and provide a real avenue for productive discussion.

We can go further still. This person has suggested that science is worthwhile because it can improve human lives and lead to a better world. The previous point
notwithstanding, we still have no real basis for optimism or hope for the future without God, because even under the best case scenario there’s no way human science can
achieve any lasting goals. Even secular evolutionary scientists freely admit that our planet is ultimately doomed, because our only source of the energy we need for life,
the sun, is going to eventually burn out and be extinguished:

“All things must end. That’s true for us, that’s true for the Earth, and that’s true for the Sun. It’s not going to happen tomorrow, but one day in the far future, the Sun will
run out of fuel and end its life as a main sequence star and die.”3

A better future?

Wait a minute! If we know we’re ultimately doomed as a species, then why do we hear so much grandiose optimism for the future coming from scientists? No matter how
many skyscrapers we build, or how many cures for diseases we find, we will all have to die one day—as Jesus pointed out in Matthew 6:27, our worries and efforts cannot
even add one hour to our lives. Even in a hypothetical scenario where science did succeed in greatly expanding human lifespans, we cannot live without the sun! Yet the
problem is worse. Even if we were to advance to the point that we could fly to some distant star and recolonize a totally new planet, that planet would eventually become
uninhabitable as well. This is called entropy—all things are winding down—and ultimately the whole universe will be devoid of usable energy.4 So, in other words, there’s
nowhere to run. We are doomed, and all science is doomed to ultimately be fruitless and forgotten. Science alone cannot offer us hope for the future.
Only in Christ can we find true hope, because Christ is God incarnate, and God is not limited by His creation.

So, after having taken away false hope from this unbeliever, they will stand naked in the light of the truth: their worldview presents an ultimately pointless and hopeless
reality. Now the stage is set for you to present the alternative in Jesus Christ and the true Gospel. Only in Christ can we find true hope, because Christ is God incarnate,
and God is not limited by His creation. God’s power transcends the physical decay of this universe, and as such he can offer us real hope for the future.

Of course, in the real world such interactions are almost never simple, and almost never confined to only one issue. Most educated non-believers have a whole arsenal of
objections to Christianity at the ready, and dealing with all the stumbling blocks to their faith may take time. That’s why we must get to know them as a person and deal
patiently with them, and we must take the time to get informed on how to deal with a wide range of objections and issues. Yet this is the charge we must take up as disciples of Christ, who commanded us to take the gospel to the ends of the earth—that includes your neighborhood and your college campus! As the Apostle Paul writes,

“For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the
knowledge of God, and take every thought captive to obey Christ” (2 Corinthians 10:4–5).
