This question is no doubt the most important question in the universe. If God exists and the Bible is true, then we are in trouble! If God does not exist and there is no purpose to life, nor is there life after death, then we are in trouble! So this appears to be the ultimate question with crucial consequences.
Whilst the existence of God is something that we usually accept by faith, it is incorrect to say that there is no evidence for God’s existence.
Firstly, let’s see what God has to say about this subject:
Psalm 14:1 “The fool has said in his heart,’There is no God.’” (NKJV)
Psalm 19:1-4 “The heavens declare the glory of God; And the firmament shows His handiwork. Day unto day utters speech, and night unto night reveals knowledge. There is no speech nor language where their voice is not heard. Their line has gone out through all the earth, and their words to the end of the world. In them He has set a tabernacle for the sun” (NKJV)
Ecclesiastes 3:11 “…He has put eternity in their hearts…” (NKJV)
Romans 1:20 “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” (NKJV)
One day, atheists will have to appear before God to give their defence in light of God’s word. What is their solid irrefutable excuse for not believing in God’s existence? Will God accept that excuse? It appears that atheists rely on ignorance as their defence yet ignorance is not even accepted in the court of law. Why would God not be at least as strict as a worldly judge?
Without wishing to commit the fallacy of appealing to majority, most people throughout history, in all cultures, civilizations and continents believe in the existence of some kind of God. There must be something or someone causing this belief.
On a logical level, how can we know that God exists? Firstly, we cannot rely on our senses. For example, we cannot simply assume that the family or people that brought us up are our parents just because we can see or touch them. Nevertheless, we do know for sure that our parents do (or did) exist because of the impossibility for us to be born in any other way. Similarly, even if you have never met or seen a painter or builder, you will know that they exist because of the impossibility that buildings or paintings exist in any other way. In Romans 1:20 God is revealing himself by pointing out the same principle. He’s confirming that since Creation requires a Creator, we are left “without excuse”!
What other evidence is there? What about the intricacies of a cell (Psalms 139:14) and the majesty of the universe (Psalm 19:1), not to mention the effect and relationship of God in people’s lives (Romans 8:16)? Don’t all these things prove the existence of God? Indeed, they do but perhaps the greatest evidence for God’s existence is the fact that without God you cannot prove the existence of anything! In fact, you cannot even prove anything!
That’s because to prove anything you need Laws of Logic! The Law of Logic are the chain of reasoning that leads to a conclusion (see http://www.creationscience.co.uk/category/logical-fallacies/). Although most of us could not recite these Laws by heart, we all use them instinctively every day.
Yet these Laws of Logic do not make sense in an atheistic universe. Why would we have these Laws at all without a Law giver? However, these Laws make perfect sense in the Christian worldview. Why would the universe be bound by these Laws of Logic, if there is NO God who upholds all things (Hebrews 1:3 “upholding all things by the word of His power” NKJV).
Now, because we are made in God’s image (Genesis 1:27), we can in a sense think like God which is consistent within His nature and therefore, have access to God’s Laws of Logic by which we reason.
The same applies to the Laws of Nature (Laws of Physics). It only makes sense if God’s existence is true. Again, why would the universe be obliged to obey them? Why are they universal and not change with time? In the Christian worldview, it makes sense because God is omnipresent and does not change with time (Hebrews 13:8, Psalm 139:7–12, 1 Kings. 8:27, Jeremiah. 23:23-24, Hebrews 4:13, Acts 17:24-28). Therefore, these Laws are a reflection of the way He thinks and His attributes.
What is even more fascinating is that these Laws are easy to understand! Albert Einstein said “The most incomprehensible thing about the universe is that it is comprehensible“. Why is it made in such a way that our simple mind can understand it? That’s because the God who made our minds would uphold the universe in the way we can understand (Romans 1:20). It all makes sense in the Christian worldview where God has imposed a certain amount of order to the universe.
What about the Laws of Morality? It doesn’t make any sense in an evolutionary atheistic universe. Why should we behave or think in a certain way if we’re just evolved animals? Why not make up our own laws? Who decides what is right or wrong anyway? However, in a Christian worldview the Laws of Morality make sense since God decides objectively what is right/wrong, His word is absolute (Psalm 119:89, Deuteronomy 4:2) and we are responsible to God for our actions (Hebrews 4:13, Romans 14:12).
If God does not exist, then science would not make sense because there would be no reason to accept the uniformity of nature on which all science and technology depend. However, in a Christian worldview, the uniformity of the universe and nature can be relied on because God is the same yesterday, today and forever (Hebrews 13:8). Only if we know that God exists can we be sure that tomorrow’s scientific experiments would yield the same results as today’s. All this is possible in a Christian worldview because God promised consistency and uniformity in the universe (Genesis 8:22, Jeremiah 33:25).
If God does not exist, we would be no reason to think that rational analysis would be possible since the thoughts of our mind would be nothing more than the inevitable result of mindless chemical reactions.
It all makes sense in light of the Biblical God.
You see, in a way, proving the existence of God is the easiest thing to do because it’s something that everyone already knows. The Bible says that everyone knows the Biblical God because has shown himself to everyone in creation and in our conscience (Romans 2:14-15). Therefore, there is no need to come up with clever arguments to prove God’s existence because evidence is not the problem. The real problem is that people suppress the truth in unrighteousness (Romans 1:18) because they don’t want to believe in God who is rightly angry at them for their sin and rebellion (Daniel 9:5, Isaiah 1:1).
In one hand, an atheist relies on things like: logic, science, morality, rationality, consciousness, uniformity of the universe; things that make sense in the Christian worldview, yet at the same time they deny the God that makes all these things possible!
