One man's opinion

I was surfing on MSN just now when I came across this article entitled, "Beautiful Arguments with God." To me, this sounded interesting. It's not often that one comes across a "religious" article on a secular website. For those who are curious, the article is found here.
The writer of this article claims that he is an agnostic. In short, an agnostic is someone who believes that the supernatural is unable to be proven. So unlike a Christian who believes in a God or an atheist who firmly does not believe in a God - an agnostic believes that it is impossible to prove or disprove. He says in the article that he decided to read through the entire Bible. Here is where I get to the part I don't understand. In the middle to the end, he says that it is impossible for him to believe in a God who is responsible for the mass killings of thousands of people in the Old Testament. For instance, he can't fathom how a God would kill innocent Egyptian children in order to compel Pharaoh enough to let the Israelites go. He claims that God is heartless and cruel, and he doesn't want to believe in someone like that.
However, the only thing I can think is, "Did this guy actually read the entire Bible?" If so, then how can he truly believe that God is heartless? He says that he is a Jew. He goes on to say, "I don't, and can't, believe that Christ died for my sins. And even if he did, I still don't think that would wash away God's crimes in the Old Testament."
The New Testament is saturated with countless instances of God's divine love for us. For example, John 3:16 says, "For God so loved the world..." Yes, God. The God of the Israelites. It mentions God sending His Son to die for us, also. I understand that Jews don't believe that Jesus is God's Son, but I can't comprehend why. There are prophecies in the Old Testament about Christ. It speaks of Him in Isaiah and Jeremiah. Yet Jews still don't believe this?
This man claims God to be cruel. How is God cruel? Yes, He was the instigator of the deaths of those Egyptian children, but they had a way out. God gave Pharaoh countless times to change his mind and let the Israelites go. Yet Pharaoh's heart remained hardened. God is a loving God, yet He is also just. He gives us opportunities, but we must be prepared to face the consequences. For every action, there is a reaction.
So basically, this is my little rant. I'm sorry if I have gotten my facts mixed up or whatever, but I'm just trying to say that this man needs to pay a little more attention. If he did indeed read the same Bible that I have read, then I guess he must not have been reading with the same insight as Christians. Is it possible that he misunderstood it? Absolutely. I am not trying to blame him, I am just trying to point this out so that others don't make his mistakes. You must read the Bible very, very carefully. If you have questions, ask a pastor or a knowledgeable Christian friend. God will open your eyes to His word if your heart is in the right place. In the words of Matthew 7:7-8, "Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened."
