Why is archaeology useful for Christians? Drawing from his experiences in the field, Dr. John Currid discusses how archaeology can be used to help believers better understand the Scriptures. The purpose of archaeology is not to prove the Bible. My view is it’s a truth, not proof. The Bible doesn’t need to be proven; I think it stands well enough on its own. Charles Spurgeon said trying to defend the Bible is like trying to defend a lion: it can defend itself. I would say that there are two things that we need to keep in mind when we consider why archeology is something that ought to be understood and used by Christians.
