What would you do if an athiest came up to you randomly and asked you authentic questions or even simple questions to test your belief in God. How would you respond or answer these questions from them?:
1) Does God have free will?
2) If human evils must be allowed so that we can have free will, then why did God also create natural evils? (i.e., floods, disease, etc)
3) Why are there over 30,000 Christian denominations all claiming to be the "true Christians"? Which one should I follow and why?
4) Is predestination true? If yes, then do we truly have a say in our Salvation? If not, then don't you have blind faith?
5) Can God create a rock too big for Himself to lift?
6) If religion and Christianity are separate, how did religion come into Christianity?
7) If Christianity is good, what about those other religions that teach the same moral conduct?
8) If God is so perfect, then why did he create something so imperfect allowing pain, suffering and daily atrocities?
9) If God is omnipotent (all-powerful), why did he take six days to create everything? Why not speak everything into existence all at once?
Interesting questions. Here are my answers based off of what I know. Please keep in mind, this is my own personal perspective.
1. Does God have free will?
Of course, God is God, surely the one who Created has the most right out of any other to do anything He so pleases.
2. If human evils must be allowed so that we can have free will, then why did God also create natural evils? (i.e., floods, disease, etc)
Firstly human evils weren't allowed to allow humans to have free will. Human errors and evils merely point to the observable fact that mankind has free will. It's as simple as having the free will to choose to hurt yourself as much as it is to have free will to choose not to hurt yourself (but we'll come back to this point)
Secondly, natural "evils" can be explained off for a various of reasons from God's punishment, to punishments mankind brings on itself. For instance God flooded the entire Earth because pre-Flood man become intensely wicked. On the other hand for a more modern example of natural disasters one could argue some natural disasters we face today are because of mankind not properly managing the Earth according to Biblical and godly principles, thus inducing "climate change." For example God instructs society in the Mosaic Law how to run a clean society simply by segregating waste product. We can clearly see in some civilizations today where sanitation is not properly maintained at the minimal Biblical suggestions that often disease and other ill environmental events are the result.
3. The many Denominations.
My view point is there is no such thing as denominations. There can only be Christianity. Either a so-called denomination is Christian or it is not. If the denomination is not Christian we need not bother with that any longer. For the denominations that are plausibly Christian my belief is they are the result of Man's thinking. For instance the Catholics are Christian so are the Protestants. However they have disagreement over Man's thinking whether or not the Pope ought to wield political power. Whether or not the Pope is infallbile is not even really an argument for or against Christianity, nor is it a pre-requisite for salvation, but is what I term a Debate of Man.
4. Is predestination truth.
No and yes. This is a big theological debate within the Debate of Man. I would contend that no person is set aside to go to the lake of fire, BUT that God being God all ready knows where each individual's choices will lead them.
5. God creating a rock too big for himself paradox
Again this is a Yes and No answer. God could create a rock big enough to be unable to lift, but then that rock would become a god wouldn't it? So in that sense no God cannot create a rock too big for himself to lift. However, consider the prophecy of the "Stone that the builders reject that became the cornerstone." God IS the rock too big for any man to lift, that stone is Jesus.
6. If religion and Christianity are separate, how did religion come into Christianity?
Easy answer; religion is just a belief system. Even atheists, though they don't like to admit it, are religious and have a religion unless they are incapable of thought. Christianity is merely the oldest known belief system. The belief system that God is Salvation, which is the name of Jesus, whom is the prophesied Messiah or Christ which means the Anointed one whom followers of the Christ are named after hence the term Christians.
7. Why do other religions have similar moral conducts?
Now this is a bit more complex to answer because God created humanity and through human history mankind has retained knowledge of morality. As we know a religion is just a belief system, even an atheist is going to have similar morals to a Christian (perhaps in a simple example of not wanting to commit murder.) All religions whether they have deities or not do have similar morals. So then why do we have all different religions be a better question to examine.
Where the other religions differ is that their traditions have obscured the meaning of Morality, often twisting morality into something to fit into Man's Debate. This even happened to the ancient followers of God. The Pharisees are a good example of this in that they had all the morals and guidelines and were quick to condemn those that broke said guidelines to a violent death of stoning, yet they themselves had turned into worshipping Man's law which means they committed idolatry and did not trully understand the law, and ironically broke their own morals whilest accusing others of breaking their morals. We can illustrate this also with just about any other religion. For instance in Islam greatest offense is to be worshipping idols in Christianity you should not worship idols also, yet by that own scrutiny, islam breaks its own rules by being the verified #1 idol worshippers on Earth with the #1 abomination being worshipped in history as we can verify it today residing in the city of Mecca. Or for instance, atheists like Christians are commanded to be scrutinous of religions and the supernatural by their morals, but atheists take their skepticism so far to blinding themselves that there is no supernatural, yet if an atheist accepts even just one of man's laws they have broken their own morals since all morality and theory of law is attributed to supernatural beings. (Plus they ironically must then discount literally just about all written history until the 1800s AD.) Buddhists morals strive for unattachment to the world like Christianity yet Buddhism also promotes worshipping idols which are vain images made of the earth breaking not just Christianity, but their own moral code as they have attached themselves to earth in the process. And so the examples can go on, but I think this is sufficient to prove my point.
8. If God is perfect why is the world imperfect.
Simplest of all the questions to answer and this ties into the other questions and answers. Reading the early parts of Genesis God made the world perfect where there was no pain or suffering or even death. Man Kind had freewill from the beginning but being made good chose not to do evil and there was no hurt in the world. However, an animal beguiled Man Kind with subtle lies and thus mankind forsook God by listening to the dragon and allowed death to enter the current world when Man Kind chose to eat death because Man was mislead. Essentially it is Man Kind's fault for messing up the perfect Creation, though the ultimate responsibility for causing death to enter the world falls upon the snake that tricked man into accepting death.
9. If God is omnipotent, why 6 days for creation?
Well this one I cannot answer for you since I am not the Creator nor did I sit and watch it all happen, however either way be ye Christian or not we gotta play by the assumption of God is God. I would say that if we all ready establish that God has free will and is God (thus the ultimate being); is not the Creator allowed to create as fast or slow as He wishes? Lol to use a secularist parable; how could Frodo argue with Tolkein that he is not the author of LOTR because Tolkein claims to have taken a few years to write LOTR instead of writing LOTR all in one day?
Hope any of these answers help demystify somethings for you. Either way very intriguing topic and I enjoyed answering and I hope you the best in your quest to find God brother.
