Can seeking arguments against Christianity strengthen Christianity? Some take the position that some knowledge is the work of Satan.  Some take the position that critical analysis can strengthen good ideas and weaken bad ones.  Should Christians seek out information that is antithetical to their faith?
If I may, here is my idea of the scientific view: yes, it can. If you look for arguments against Christianity, thinking that you may find some, but you don't find any, this is evidence in favor of Christianity.

Evidence, you see, is all about correlation. Whether or not your shoes are untied is strongly correlated to whether or not they appear to be untied. So, when you see that your shoes appear to be untied, you can conclude, with great certainty, that they actually are untied.

Likewise, Christianity is correlated with arguments. Whether or not Christianity is true is correlated with whether or not there are good arguments against it. If there are good arguments against it, this is evidence that it is false; if there are not good arguments against it, this is evidence that it is true.
