Reasonable Arithmetic

There is certainly no shortage of Christian writing which aims to demonstrate the reasonableness of Christian belief. For example, take this list of popular books / sites:

• Reasonable Faith
• str.org (Stand To Reason)
• The Reason For God
• Faith and Reason
• Reasons To Believe
• Reasons For Faith
• The Case for the Real Jesus
• Love Your God With All Your Mind
• Compelling Evidence for God and the Bible

What do these books tell us about the reasonableness of Christian belief? We could (and ideally should) read them all and formulate our own opinions. However, we can ascertain one conclusion without even opening the books: Christianity struggles to present itself as reasonable. You would never see a book on the shelf titled "Reasonable Arithmetic", because arithmetic doesn't struggle to demonstrate its reasonableness.
