Sorting out the Christian essay topics is a laborious and time consuming process, as you have to become familiar with specific terms and historic events described in the Bible in order to understand what you are writing about. Try to select one of the Christian essay topics that you are familiar with to some extent, so you can handle it. Choose a topic that has kind of a hook and not only relates to Christianity, but also is of interest to you, as working with something that is interesting gives better results and makes the process of working more enjoyable.
Here is another example of a simple error of omission that could have been caught if the student had read the essay aloud or given it to a friend to read. The word "of" should be between "calculation" and "the." That one small error makes the entire sentence awkward and confusing. If the instructor has to reread the sentence to try to understand its meaning, the flow of the essay is interrupted. If this happens often enough in the essay, it gives an overall bad impression on what otherwise might be a very good paper in terms of research.
