This will be a short one. I hear the objection raised by non-Christians all the time that if God existed, he wouldn't or couldn't have communicated with us. Frankly, I don't understand such arguments, which are so irrational that I just have to shake my head at the person who makes them.
Clearly, if God exists then He is responsible for everything else that exists as well. If God exists then He is responsible for all the matter in the universe, for every physical and natural law, and for life, consciousness, and rationality. To make the claim that God has the power to create everything from nothing at all, but now doesn't have the power to communicate with His creation is a sign of a mind not functioning well. And yet, I cannot count the number of times I have listened to agnostics, and even theists, make this exact claim.
I imagine that this position is taken by people because they have not experienced a personalized communication from God. After all, if He exists and wants us to believe in Him, the best way to achieve this goal would be to throw back the curtain for all to see and announce His presence to the world. Since He doesn't do this, He is either incapable of doing so or He doesn't exist.
The problem with this kind of thinking is glaring. Those who make the argument are assuming that God is just like them, something which actually goes against the teaching of scripture (Numbers 23:19). They assume that God would behave in this way if He could; because that's the way they think they would behave if they were in His place.
Christians believe that God has already communicated the bulk of what He wants or needs to communicate in a little book known as the Bible. The real issue here for most people is not whether God can speak to us, but whether He already has spoken; through the pages in the Bible. But is the Bible reliable? Many people say that it isn't that it's just full of contradictions and errors. Clearly, the Creator God, if He chose to communicate through the pages of a book would have done a better job than what we find in the Bible, or so they say.
We'll take a look at that problem over the next several posts.
