Thinking Like A Christian - Defending Your Faith
Session 2: Does God Exist?
1) Does God Exist? (Is There Really a God?)
A) The first question that must be answered
B) Without God, there is no moral being against whom we have sinned, therefore, there is no need of salvation
C) Without God, there is no acts of miracles, and Jesus is either a liar or a lunatic
2) Reasons for Believing There Is A God
- Traditional Arguments For The Existence of God)
A) Cosmological
Ð
(cosmos = creation) argument from creation
i) Basic idea is that since there is a universe, it must have been caused (or created) by something greater than itself
ii) This is based on the law of causality: every limited thing is caused by something other than itself
(1) This argument takes two forms:
(a) The universe needed a cause at its beginning
(b) The universe needs a cause right now to continue existing
iii) Affirmations of the cosmological argument:
1. The universe had a beginning.
2. Anything that has a beginning must have been caused by something else.
3. Therefore, the universe was caused by something else, and this cause was God.
Rom. 1:18 ¦ For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness,
Rom. 1:19 because that which is known about God is evident within them; for God made it evident to them.
Rom. 1:20 For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.
iv) Arguments against the cosmological argument
1. Scientific Objections to an Eternal Universe
á It is impossible to show that the universe, so far as its substance is concerned, has had a beginning.
á If the universe had no beginning then argument from creation is not valid.
á The principle of causality does not require a first cause, only a cause.
á Astronomical observations indicate that the universe had a cataclysmic and sudden beginning.
á The Big Bang
á The second law of thermodynamics states that the universe is running out of usable energy.
á It therefore could not be eternal.
2. Philosophical Objections to an Eternal Universe
á It is impossible to pass through an infinite series of moments.
á You can never finish an infinite series of real things.
á If the past is infinite (which means that it never had a beginning) then we could never have passed through time to get to today.
á It is impossible for anything infinite to exist as part of the universe.
á This is because it is always possible to add one to it.
á By definition if you can add to something it cannot be infinite.
3. The Cause for Continuing Existence
á The universe needs a cause for its continuing existence.
4. Objections to the Cosmological Argument
á The principle of causality only requires a cause greater than the universe.
á Many claim that it is impossible to prove that this cause is not finite.
5. Why Does Anything Exist?
á Finite, changing things exist.
á Every finite changing thing must be caused by something else.
á Limited changing things do not have independent existence.
á There cannot be an infinite regression of causes.
á Therefore, there must be a first infinite and unchanging cause of every finite, changing thing that exists.
á Even if one can show that the universe had a cause it is impossible to prove from the Cosmological Argument that this cause had to be the God of Christianity.
v) Usefulness: The Value of the Cosmological Argument
á It argues for the universe having a cause greater than itself.
á And while not proving the God of Christianity it certainly is compatible with the Christian view of God.
á Non-compatibility is a major stumbling block for any scientific based argument; remember, it is futile to discuss the possibilities of a miraculous event done by God to a person who does not accept the existence of God in the first place!
B) Teleological
Ð (telos =
purpose) Argument from the evidence of design and purpose seen in the universe
á The order and useful arrangement of a system implies intelligence and purpose as its organizing cause.
á The universe is characterized by order and useful arrangement; therefore, the universe has an intelligent and free cause.
á All designs imply a designer.
á There is a great design in the universe.
á Therefore, there must be a Great Designer of the universe.
á The principle of causality leads us to expect this.
á "Watches imply watchmakers, buildings imply architects; paintings imply artists, and coded messages an intelligent sender." (p. 20)
á No one coming across a Rolex watch would think that the watch had been created by accident!
á Great Literary Works Don't Happen By Accident
á A monkey could never type one of Shakespeare's plays.
á A thousand monkeys could never type Hamlet in a billion years!
á There Is Much Design In The Universe
á Life is very complex.
á A single DNA molecule carries the same amount of information as one volume of an encyclopedia.
á But no one would think that an encyclopedia happened by chance.
i) Limitations
á It cannot prove that God is personal.
á It also cannot prove either
á the unity
á the eternity
á or the infinity of God.
ii) Usefulness
á It demonstrates the reasonableness of believing in God as the creator responsible for the order, harmony and complexity of the universe.
á The implications of the Teleological Argument do not prove the God of Christianity. But the God of Christianity is certainly compatible with those implications.
C) Ontological
Ð (ontos = being) argument from being
- This is a useful complement to other arguments, but is the weakest proof of the existence of God on its own merits.
- Attempts to prove that God must exist by definition. (p. 24)
- Contends that the idea of God necessarily involves the attribute of existence.
- This
argument takes several forms.
á Ontological Argument # 1
á Whatever perfection can be attributed to the most perfect Being possible (conceivable) must be attributed to it (otherwise it would not be the most perfect being possible).
á Necessary existence is a perfection which can be attributed to the most perfect Being.
á Therefore, necessary existence must be attributed to the most perfect Being. (pp. 24-25)
á Question: Has this argument the unstated assumption of philosophical idealism?
á Question: Is this argument guilty of circular reasoning?
á Evaluation of Argument # 1
á "This argument succeeds in showing that our idea of God must include necessary existence; but it fails to show that God actually exists. It shows that we must think of God as existing necessarily; but it does not prove that He must necessarily exist." (p. 25)
á An Illustration
á Someone recently told me of a person who told them that they were not an atheist because they believed that God existed. However, they believed that he existed only in their mind.
á The second statement of the Ontological argument is useful in dealing with these types of situations.
á Ontological Argument # 2
á If God exists, we conceive of Him as a necessary Being.
á By definition, a necessary Being must exist and cannot not exist.
á Therefore, if God exists, then He must exist and cannot not exist.
á Evaluation Of The Ontological Argument
á The argument never really gets past the initial "if." It never gets around to proving the big question that it claims to answer. The only way to make it prove that God exists is to smuggle in the argument from Creation. It can be useful, though, because it shows that, if there is a God, He exists in a necessary way. (pp. 25-26)
D) Moral
Moral-
(axios = judgment) Argument from humanityÕs sense of moral law
i. Moral Argument for God
a.
Mankind has an innate
experience of morality.
b.
We experience some things as
"right" and other things as "wrong.Ó
c.
MankindÕs sense of moral
justice cannot be explained by evolutionary progress because this sense of
morality often leads one to do what may be detrimental to his well being.
d.
The most reasonable
explanation for this sense of morality is that it was created by a moral and
holy God who created mankind in his image. (Rom 2:14-15)
14 Indeed, when Gentiles, who do not
have the law, do by nature things required by the law, they are a law for
themselves, even though they do not have the law, 15 since
they show that the requirements of the law are written on their hearts, their
consciences also bearing witness, and their thoughts now accusing, now even
defending them.
ii.
What Kind of God Exists? (or
the nature or attributes of God)
a.
According to the Bible, there
is much that can be known about God apart from GodÕs special revelation found
in the Bible (Rom. 1:18).
b.
The arguments for the
existence of God imply (indicate) much about GodÕs nature.
c.
GodÕs nature can be summed up
in a philosophical position known as the Òmoral argumentÓ
i)
Moral Argument
1.
Argues that the cause of the
universe must be moral, in addition to being powerful and intelligent. (p. 22)
2.
All people are conscious of
an objective moral law.
3.
Moral laws imply a moral
Lawgiver.
4.
Therefore, there must be a
supreme moral Lawgiver.
ii) Immanuel Kant (1724-1804)
1.
Rejected the traditional
arguments for the existence of God.
2.
Approved of the moral
argument as a way to show that God is necessary for moral living.
iii)
Important Distinction
1.
Unlike physical laws, moral
laws donÕt describe what is but rather what ought to be.
2.
Therefore, any moral ÒoughtÓ
must come from beyond the physical universe.
3.
ÒIt transcends the natural
order and requires a transcendent cause.Ó (p. 23)
iv)
Moral Relativism
1.
Is The Unofficial Creed Of
Much Of Western Culture.
2.
Both Political Correctness
And Multiculturalism Presuppose Moral Relativism And Deny Objective Truth.
v) If One Denies Objective Moral Truth
One Must Admit
1.
That Mother Teresa Was No
More Or Less Moral Than Adolf Hitler.
2.
That Torturing
Three-Year-Olds For Fun Is Neither Good Nor Evil.
3.
That Raping A Woman Is
Neither Right Nor Wrong.
4.
That Taking Care Of OneÕs Family Is Neither Good Nor Bad.
vi)
Questions Asked In Our
Postmodern Age:
1.
ÒWho Are You To Tell Me What
I Ought To Prefer?Ó
2.
The Words ÒOughtÓ And
ÒShouldÓ Are Meaningless.
vii)
The Death Of Truth
1.
We Have Gotten Rid Of Truth
And In Its Place Substituted Opinions And Subjective Preferences.
2.
The Question ÒWhat Is Good?Ó Has Been Replaced With ÒWhat
Feels Good?Ó
3.
The Concept Of Moral Truth
Has Become Incomprehensible To Contemporary Society.
viii)
Rejection Of Relativism
1.
If Our Moral Intuition Rebels
Against The Consequences Of Relativism It Is Because Deep Down We Know That
Relativism Is False.
ix)
Refuting Relativism
á
Show The Contradictions Of
Relativism
á
Ethical Relativism Is Almost
Always Self-Refuting Practice
á
For Example, When A
Relativist Says, ÒYou ShouldnÕt Judge Others, You Intolerant Bigot!Ó
á
Point Out To Them That They
Are Making A Moral Judgment Against You.
á
When Someone Tells You That,
ÒYou ShouldnÕt Force Your Morality On Me,Ó Simply Ask, ÒWhy Not?Ó
á
The Relativist Is Going To
Have A Hard Time Explaining To You Why You ShouldnÕt Impose Your Views Without
Imposing His Morality On You.
á
This Question Forces The
Relativist To Give You His Moral Standard While He Is Trying To Explain To You
That Moral Rules DonÕt Exist.
x) You ShouldnÕt Force Your Morality On MeÓ One example of a
ÒpersonalÓ morality argument:
á
ÒYou ShouldnÕt Force Your Morality On Me.Ó
á
ÒIÕm Not Entirely Sure What You Mean By That Statement. Do You Mean I Have No Right To An
Opinion?Ó
á
ÒYou Have A Right To Your
Opinion, But You Have No Right To Force It On Anyone.Ó
á
ÒIs That Your Opinion?Ó
á
ÒYes.Ó
á
ÒThen Why Are You Forcing It
On Me?Ó
á
ÒBut YouÕre Saying That Only
Your View Is Right.Ó
á
ÒAm I Wrong?Ó
á
ÒYes.Ó
á
ÒIs That Your View?Ó
á
ÒYes.Ó
á
ÒThen YouÕre Saying Only Your
View Is Right, Which Is The Very Thing You Objected To Me Saying.Ó
á
ÒDonÕt Push Your Morality On
Me.Ó
á
ÒWhy? DonÕt You Believe In
Morality?Ó
á
ÒSure, But I Believe In My
Morality, Not Yours.Ó
á
ÒWell Then, How Do You Know
WhatÕs Moral?Ó
á
ÒI Think People Should Decide
Individually.Ó
á
ÒThatÕs Exactly What IÕm
Doing. And IÕm Deciding YouÕre
Immoral. WhatÕs The Problem? Live And Let Live Is Your Value, Not
Mine.Ó
á
ÒYou ShouldnÕt Push Your
Morality On Me.Ó
á
ÒCorrect Me If IÕm Misunderstanding
You Here, But It Sounds To Me Like YouÕre Telling Me IÕm Wrong.Ó
á
ÒYou Are.Ó
á
ÒWell, You Seem To Be Saying
My Personal Moral View ShouldnÕt Apply To Other People, But That Sounds
Suspiciously Like You Are Applying Your Moral View To Me. Why Are You Forcing Your Morality On
Me?Ó
iii.
Limitations Of The Moral
Argument
a.
It cannot prove a creator of
the material universe
b.
It cannot prove the infinity
of God, since mankind is finite.
c.
It cannot prove the mercy of
God but only God's justice.
iv.
Value Of The Moral Argument
a.
It shows the reasonableness
of assuming the existence of a personal God, who rules us in righteousness, and
who is the proper object of supreme affection and service.
b.
ÒEveryone expects others to
follow some moral codes, even those who try to deny them.Ó (p. 24)
