I dare you to stand up in any evangelical church service and say, "While I really believe that Christianity is true, some parts make no sense." Then sit down and see what happens. I guarantee that a wave of superficial cliches would pour out on you. "I know God is there because I sense Him in my heart . . . in a very real way, it all makes perfect sense. If you have the mind of God you would see that it is profoundly reasonable."
Like I said many times before, there is no easy path out of the pit. As a Christian, I can explain this difficulty as the mind is fallen, thus can not find its way out easily. A perfect mind would not, in theory, have this problem.
So what are my problems with Christianity.
1) God is silent. While the Christian narrative has God acting in space and time, historically, there has not been a verifiable contact with God in space and time in two millennia. Sure, miracles are attested to all the time. Sit with a group of evangelicals and you will hear of constant miracles . . . but let's get real for a moment. Raising Lazarus from the dead after rotting for three days . . . that's a miracle. Your uncle recovering from heart surgery (when 78% of patients do) is not a miracle. The Mets winning the World Series in 1969 was not a miracle. The fluttering feeling that you felt in your stomach, was not supernatural.
Now a Christian would have to assume that the reason God is silent is because it is part of His plan rather than Him being impotent. But it would certainly make life a heck of lot easier if He made a grand appearance now and then.
2) Why Was the Gospel Necessary? While I've personally explained why the gospel was necessary many, many times and even preached on it myself, it does beg the question as to why? If God is omnipotent, then He would have the ability to do things differently. He could have prevented sin from entering the world. He could have avoided the need for Christ to die on the cross. The gospel story, in ways, sounds like it could have been written by Hans Christian Anderson.
3) If the Holy Spirit's role is to purify people, why is it that Christians have no more, overall, purity than non-Christians? While Christians may drink, smoke, curse less than non-Christians, I honestly think they, in general, lie more. They lie about their motives, their witness of miracles, and even about the events of day to day life, in order to make themselves appear more spiritual.
4) Why is there this confusion between the Biblical narrative in primordial history and the scientific record? It would be much easier if the two dove tailed without question.
I will rest my case with those problems. But despite these, I am still a Christian because I believe the Christian answers, such as the problem of evil, is better than the answers of the other possibilities.
