Elsewhere he explains why he does not believe, but he never gives any logical reasons that it is incoherent to believe that God exists (similar to round squares or married bachelors).  Most of his reasons center around the concepts below. The complete article on Mr. Cline's atheist philosophy.

The atheist says:

1. all religions can't be right, so they must be wrong. 

  Response: Well obviously, there is such a thing as "truth".  2 plus 2 equals 4, no matter who says it doesn't.  The earth is round, whether everyone believes it or not.  Of course all religions can't be right.  And yes, if God left us alone and "in the dark", all religions could be wrong, but it is also possible that if there is a Creator, and if He has chosen to communicate and have a relationship with His creation, then it is not only possible, but necessary and logical that He has spoken to mankind, and that one "religion" is indeed true, and that would make the others false (since they contradict each other)  The question is, Which one is true?

2. Faith and the supernatural are unreliable

Faith in and of itself is unreliable, but faith does not exist by itself, it has an object.  If your faith is in something unreliable, then your faith is unreliable.  If your faith is in something rock solid, then it is reliable. 

What is your faith in?....     Something you believe, just because you believe it?

If you believe God does not exist, you have faith in this because you believe it, but what if you are wrong? 

If you want to trust in a supposed "prophet" that claims to speak for God, but lived an immoral life, justifying his own sins at every corner, and now leads extremists on a bloody global rampage, you are risking a lot...  what proof do you have that he was right?

If you want to believe in a deep thinker, whose opinions have been espoused across generations, that's your choice-  but who says he is right??

The object of our faith must be only that which God has clearly revealed as coming from HIM.  There is only one "religion" (and I hesitate to call it that) that is reliable.  The one that God has declared himself as the truth.  God did not trust men alone to deliver some moral message.  Though He did that through supernatural manifestations in the wilderness of Sinai, God wrote in stone with His own finger the moral commands we were to follow, but that was not enough.  Israel and we could not keep those commands, we failed God miserably.

God proves what is faithful and reliable by coming to earth Himself.  No other "religion" makes such claims, not only does the Bible claim this, but it is historically accurate. Critics used to scoff at the Bible for mentioning names and places that were recorded in no other sources outside the Bible.  But now, time and again, for more than a hundred years archaeology continues to prove historical facts that only the Bible recorded.  Those that witnessed the death and resurrection of Jesus Christ and recorded it in the Bible gave their lives in testimony of the truth of their accounts.

Jesus came not only to deliver a body of truth in which we should believe, but Jesus Himself is the way, the truth and the life.  So we could be forgiven and restored to a right relationship with God, He offered himself as an innocent sacrifice for the sins of the entire world.  How could He do that, you say?  God chose to do it this way, who are you to question it?  He has proven it by raising Christ from the dead, and ascending up into heaven in front of many witnesses!  Can you do that?

3. Throughout the history of the world, the various ideas of who God might be and the behavior of many of those that espouse those beliefs have been immoral and inconsistent, and this inconsistency, evil and immorality of the world disproves the existence of God.

There is no logic in this line of thinking.  Where is the "round square" here?  Just because God is good and we are not does not disprove His existence.  Because man has made up all kinds of ideas and religions to explain God and our existence, and just because we were wrong about most of them, doesn't make God not exist!   Our mistakes and shortcomings don't eliminate the true God.

This is why it is important for you to find out how God has spoken to us.   God has communicated with us and HE has explained why there is evil in the world, and HE has done something about it!  In the letter to the Hebrews, chapter 1, God tells us:

In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.

Choose your response:

It does seem to warrant investigation, and I am ready to consider the possibility that there could be God of some sort

Maybe it does warrant it, but I know you are coming from a Christian perspective, and I see many Christians that are anything but wholehearted in their investigation and pursuit- how can what you are saying be true?

I don't know if I'm sure or not, and it really doesn't matter.  I still have major doubts about the existence of God.  I'd like to take another route of discussion about it.
