As “natural
proofs”—that is, as arguments based on man’s observation of and
reasoning about nature—these “proofs” do not logically prove
the existence of the true God. Louis Berkhof writes that “none of
them can be said to carry absolute conviction.” Of course, this
fact means not that the existence of God is contrary to logic but
rather that these arguments fail to demonstrate the existence of God
in a compelling way to those who suppress the truth in
unrighteousness (Rom. 1:18). Instead, they must be considered in
concert with biblical presuppositions—namely, that the God of the
Bible exists, that he is one, and that he is sovereignly powerful
over all creation. While God has given sufficient evidence of his own
existence in creation and conscience, the unregenerate suppress the
truth of general revelation in unrighteousness (Rom. 1:18–21).
Therefore, all people have within them the awareness that God exists,
but in their depravity they suppress and corrupt the knowledge of God
revealed in nature.
Because
man’s depravity is total, the curse of sin reaches even to man’s
mind, so that his thinking is futile, his understanding is darkened,
and he walks in ignorance (Eph. 4:17–18). As a result, the natural
man’s faculty of reasoning is corrupted by sin. For this reason,
believers cannot and should not rely merely upon the “natural
proofs” as evidence for the existence of the true God.
In fact, a
significantly more radical change must take place for sinful man to
come to a true knowledge of the triune God of Scripture. As those
whose minds have been blinded to the glory of God revealed in Christ
(2 Cor. 4:4), unbelievers do not need more evidence, whether logical
or empirical; rather, they need new eyes to properly evaluate the
sufficient evidence they already have. They need to experience the
miracle of regeneration, in which God quickens the unbelieving heart
by shining into it the light of the knowledge of his glory (2 Cor.
4:6). This happens only by the proclamation of the gospel that Jesus
Christ is Lord (2 Cor. 4:5).
In the
final analysis, then, only the gift of saving faith, imparted by the
Holy Spirit through the Word of God (Rom. 10:17; James 1:18; 1 Pet.
1:23–25), supplies the basis for the knowledge of God (Heb. 11:1,
6). As Berkhof observes concerning Christians, “Their conviction
respecting the existence of God does not depend on them [the ‘natural
proofs’], but on a believing acceptance of God’s self-revelation
in Scripture.” Christians believe that God exists because God has
shone the light of his self-authenticating glory into their hearts
through the Word of God.8
Nevertheless,
the “natural proofs” do serve valid ministry purposes—when they
are seen not as humanly derived proofs but as God-given biblical
summaries of natural revelation and testimonies to the existence of
the God of the Bible. As Berkhof helpfully explains,
They are
important as interpretations of God’s general revelation and as
exhibiting the reasonableness of belief in a divine Being. Moreover,
they can render some service in meeting the adversary. While they do
not prove the existence of God beyond the possibility of doubt, so as
to compel assent, they can be so construed as to establish a strong
probability and thereby silence many unbelievers.
Bavinck
adds, “But though they are weak as proofs, they are strong as
testimonies. They do not force the mind of the unbeliever, but they
are signs and testimonies which never fail to leave an impression on
the soul of any person.” Therefore, the “natural proofs” can
instruct and encourage the believer and silence the unbeliever but
only when they are drawn from Scripture and so partake of the unity
of Scripture. Only then will these arguments function as they are
designed: a valid part of proclaiming the gospel as a testimony to
the existence of God.
An
important model of properly arguing for the existence of God is
Paul’s sermon to the Greek philosophers on Mars Hill (Acts 17). It
is important to note, first, that Paul did not engage in dialogue but
preached a sermon. He said, “For as I passed along and observed the
objects of your worship, I found also an altar with this inscription,
‘To the unknown god.’ What therefore you worship as unknown, this
I proclaim to you” (Acts 17:23). Paul preached to the philosophers.
In so doing, he drew on the Old Testament theology of God and
creation and applied it against the false beliefs of Epicureanism,
Stoicism, and other philosophies about God, nature, purpose, death,
and sin.
For
example, Paul proclaimed that God is the transcendent, personal,
sovereign Creator by his imperial power: God “made the world and
everything in it, being Lord of heaven and earth” (Acts 17:24).
This statement reflected Old Testament theology (cf. Gen. 1:1; Ex.
20:11; Isa. 42:5) and directly contradicted the Epicurean view that
everything came about by the chance concourse of eternal atoms.
Paul’s assertion also stood against the Stoic concept that
everything in the world originated from a fatalistic, impersonal,
rational principle (the logos).
Also, Paul
confronted the Epicureans with the Old Testament truth that the
personal, sovereign God exists independently of man-made buildings:
God “does not live in temples made by man” (Acts 17:24). Paul did
not deny that God could manifest his presence in earthly buildings
such as the Old Testament tabernacle and temple, but rather, Paul
denied that God needed physical buildings to live in. This statement
was also Old Testament truth. In reflecting on the temple that God
told Solomon to build, Solomon said to God, “But will God indeed
dwell on the earth? Behold, heaven and the highest heaven cannot
contain you; how much less this house that I have built!” (1 Kings
8:27). And later, Isaiah delivered a message from God: “Thus says
the Lord:
‘Heaven is my throne, and the earth is my footstool; what is the
house that you would build for me, and what is the place of my
rest?’ ” (Isa. 66:1). Paul’s use of Old Testament theology
opposed the Epicurean belief that the gods lived in temples made with
human hands.
Paul
similarly focused Old Testament theology against the Stoic and
Epicurean beliefs about man’s duty to serve the gods properly. The
Stoics taught that man should live by impassively accepting and
conforming to impersonal fate. They believed that one should live by
the principle of apatheia
(passionless indifference). The Epicureans taught that man should
serve the gods by the principle of atarxia
(mental pleasure), which, to them, was a lack of desire for any
pleasure. The Stoics and the Epicureans had differing views about
what service to the gods should look like, but both systems believed
that the gods needed man’s service. Paul did not deny that man
should serve God, but he did deny that the true God needed man’s
service: “nor is he served by human hands, as though he needed
anything” (Acts 17:25). Paul could have also shown that the Old
Testament concept of duty to God was a matter of love for God (Deut.
6:4–25). Regardless, Paul clearly preached Old Testament theology.
The true, sovereign God needs nothing from man:
I will not
accept a bull from your house or goats from your folds. For every
beast of the forest is mine, the cattle on a thousand hills. I know
all the birds of the hills, and all that moves in the field is mine.
If I were hungry, I would not tell you, for the world and its
fullness are mine. (Ps. 50:9–12)
Yet another
example of Paul using Old Testament theology to challenge the false
beliefs of the Epicureans and Stoics is Paul’s preaching that God,
as the personal, sovereign Creator, governs the life of man and the
world by his providence. He provides to all people what they need to
live: “He himself gives to all mankind life and breath and
everything” (Acts 17:25). And God has given people their national
life with its time and boundaries: “And he made from one man every
nation of mankind to live on all the face of the earth, having
determined allotted periods and the boundaries of their dwelling
place” (Acts 17:26). This message opposed the Epicurean belief that
life arose from the blind-chance concourse of atoms and that
everything in history has occurred because of man exercising his free
will in cooperation with an impersonal nature. And Paul’s preaching
was against the Stoic assertions that life was by the impersonal,
fatalistic logos
principle and that the nations and all things in history ultimately
had no distinctions and resulted from impersonal fate. These
teachings echoed Old Testament theology. God personally created all
things and gave life to all living creatures (Isa. 42:5), and he
foreordained the political existence and boundaries of the nations:
“When the Most High gave to the nations their inheritance, when he
divided mankind, he fixed the borders of the peoples according to the
number of the sons of God” (Deut. 32:8).
In
proclaiming the gospel based on an Old Testament theology of God and
creation, Paul expressed (1) that God is the personal First Cause and
designer of all creation, (2) that he is independent of the world but
sovereign over it in directing his determined course for it, (3) that
all life is from him and depends on him, (4) that he is the source
and final Judge of morals, and (5) that he has provided a way for
sinners to be spared final judgment through repenting of sin and
idolatry. So Paul used aspects of the various “natural proofs,”
yet he derived these concepts not from human reason but from God’s
self-revelation in the Old Testament. Thus Paul used a quotation from
the pagan Greek poet Epimenides (ca. sixth century BC) not as a
source of truth but to illustrate to the Aereopagites that their own
cultural icons knew the truth even if they denied it (Acts 17:28; cf.
Titus 1:12). He proclaimed God’s revelation to refute the false
theism of the Greek philosophers, demonstrating that the “natural
proofs” for God’s existence must not ultimately appeal to human
perception or reason but to God’s own self-revelation in Scripture.
In summary,
God exists. He exists as he is revealed by the Bible. The reason one
must believe that he exists is because he said that he exists. His
existence must not be accepted on the basis of human reason, because
that is limited to time and space and has been corrupted by
indwelling sin. God has sufficiently revealed himself in the Bible,
but he has not revealed himself exhaustively. Man can know only what
God has revealed in Scripture about his nature and works. But that is
sufficient for people to know him in a personal, saving relationship.
One way God has sufficiently and personally revealed himself to man
is by describing himself in Scripture by several different names. It
is to the names of God that we now turn.1
