I post about several different things here: church planting, theology, church life, and writing.
Here is a little bit of grammar for you. Always use a comma before a conjunction in a list. For example: I like the colors red, blue, and green.
Some people might say you don't have to use a comma, but it is always better safe than sorry. Take this quote for example from the ContraCostaTimes: "The survey provided information about religion, school culture, curriculum, race relations, discipline, exposure to violence and homework." Most schoolchildren would say that exposure to violence and homework are the same thing. And all students are exposed to homework whether they like it or not. It would have been better to have the comma there in order to avoid the weird sentence construction.
Just another example of me on a soapbox!
