I want to write a work of Christian apologetics, but for that I need a lot of arguments. I know some, but not enough of them, and the ones I know may not be perfectly solid. So I need to do research, but I don't want to spend money on books. So I will need to use the internet. My question is this: How do I conduct research on the internet and get the most out of it without paying for anything. My question is particularly this, how do I research this topic of Christian apologetics? Do you think I will find enough information on google books for free? Also, do you think I should gather only a small number of the best arguments and use them, so that my work is not too long? I want to make a clear case for the Christian faith but I don't want to write 100 to 700 pages. What do you think I should do?
