Can we know that God exists by reason alone?

Answer 1

There are tens of reason-based proofs for God's existence. These have been recorded for centuries and are easy to look up. However, this subject ultimately becomes one of personal belief, since our possession of free-will mandates that it be possible to put forth arguments (fallacious or not) against every one of the proofs.
Here are a few.
1) Teleological Argument: The universe has definite design, order, and arrangement which cannot be sufficiently explained outside a theistic worldview. (This is how Abraham, without benefit of teachers, came to reject the chaotic world-view of idolatry and the possibility of Atheism). For example, theoretical physicist and popular science writer Paul Davies (whose early writings were not especially sympathetic to theism) states concerning the fundamental structure of the universe, "the impression of design is overwhelming" (Davies, 1988, p. 203).From the complexities of the human eye to the order and arrangement of cosmology, the voice of God is heard. God's existence is the best explanation for such design. God is the designer.Is there evidence against Evolution

2) Anthropic Principle: The laws of the universe seem to have been set in such a way that stars, planets and life can exist. Many constants of nature appear to be finely tuned for this, and the odds against this happening by chance are astronomical. Professor Russel Stannard (a particle physicist) states: "The universe has been bent over backwards in order that intelligent life should exist...must have known we were coming."

3) Sensus divinitatus: The innate sense of the divine exists within all people. People and cultures of all time have, by instinct, sensed a need to worship something greater than themselves. No ancient societyever existed that did not believe in a supernatural power.

4) Tradition: There are events in human history which cannot be explained without God. Many people have their subjective stories that bend them in the direction of theism, but there are also historical eventssuch as the Giving of the Torah to over two million people at Mount Sinai, which are underpinnings for the belief in God.

5) Pascal's Wager: Belief in God is the most rational choice due to the consequences of being wrong. If one were to believe in God and be wrong, there would be no consequences. However, if one were to deny God and be wrong, the consequences are eternally tragic. Therefore, the most rational choice is not agnosticism or atheism, but belief in God.

6) Logic. Why is there reality rather than nothing? Aside from God's creating it, there are only five options:
a) The universe is eternal and everything has always existed.
- Even atheists have abandoned this possibility, especially because it would violate the Second Law of Thermodynamics.

b) Nothing exists and all is an illusion. There is no reality; there is only nothing.
- This possibility, it should be obvious, is completely self-defeating. In order to even make such a proposition, the subject has to exist in some sense. If all is an illusion, where did the illusion come from? Even the solipsist, who does not believe in the existence of other minds, has to explain the genesis of his own mind.

c) The universe created itself. This is the idea that the universe and all that is in it did not have its origin in something outside itself, but from within.
- Like with the previous two, this makes a logical absurdity. It would be like creating a square triangle. It's impossible. A triangle by definition cannot be square. So creation cannot create itself as it would have to pre-date itself in order to create.

d) Chance created the universe. The odds of winning the lottery are not very good; but given eons of time, everyone will win. While the odds of the universe spontaneously appearing are not minuscule, could it happen, given enough time?

- This option is a dishonest sleight of hand that, like "survival of the fittest," amounts to nothing, because it implies that "chance" itself has quantitative causal power.
The word "chance" refers to possibilities. It does not have the power to cause those possibilities. It is nonsense to speak of chance being an agent of creation, since chance is not a force. "What are the real chances of the universe being created by chance? Impossible. Chance is incapable of creating a single molecule, let alone an entire universe. Why not? Chance is no thing. It is not an entity. It has no being, no power, no force. It can effect nothing because it has no causal power within it. It is a word which describes mathematical possibilities which, by the curious flip of the fallacy of ambiguity, slips into the discussion as if it were a real entity with real power, the power of creativity." (R.C. Sproul, Not a Chance. Grand Rapids, MI: Baker, 1999.)

e) The universe is created by nothing. Simply put, nothing created the universe.
- The problem here is that it is either a repetition of option "a" (the universe is eternal) or fails due to the irrationality of "d." In our current universe, the law of cause and effect cannot be denied by sane people. While we often don't know what the cause of some effect is, this does not mean that there was no cause. When we go to the doctor looking for an explanation for the cause of our neck pain, we don't accept the answer "There is no cause. It came from nothing."

Answer 2

Theology is a field in which 'reason' almost always tells us what we already believe about God. For example, over the centuries, theologians have sought to use reason to prove that God exists, using philosophical arguments that they believed to have made the point. Each of these arguments has fatal flaws and only tells us what the proponents already believed, which was that God exists. In fact, some of these arguments could equally be used to prove that the Hindu god Brahma exists, but with the same fatal flaws of reasoning.

If we must begin from existing assumptions, nothing meaningful can be ascertained about God by reasoning. If we first accept the possibility of his non-existence, then reasoning can establish that God's existence is unknowable. If we require empirical evidence, then reasoning can tell us that God's existence is unproven and unlikely.

Another Answer:



God reveals Himself in two ways. The first is His written revelation, The Bible. "All Scripture is given by inspiration of God" (2 Timothy 3:16).

The second is the evidence of creation, because it was "God who created all things through Jesus Christ" (Ephesians 3:9). Every creature is evidence and proof of a genius Creator. There is always cause and effect, and the cause of creation is our Creator God.


The Apostle Paul spoke of those who "worshiped and served the creature rather than the Creator" (Romans 1:20-25):


Romans 1:20-25New King James Version (NKJV)
20 For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, 21 because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened.22Professing to be wise, they became fools, 23 and changed the glory of the incorruptible God into an image made like corruptible man-and birds and four-footed animals and creeping things. 24 Therefore God also gave them up to uncleanness, in the lusts of their hearts, to dishonor their bodies among themselves, 25 who exchanged the truth of God for the lie, and worshiped and served the creature rather than the Creator,who is blessed forever. Amen.

Answer 4

The world had to form some way that's the only reason

Answer 5

There is no reason. Either you believe there is a God, or you don't. It is all a question of personal faith.

Answer 6

no
