If you knew that you were about to get into a conversation with an Atheist (or a Buddhist or a Wiccan) how would you feel about it? Fear? Frustration? Nervousness? If so, why?
Unfortunately, most Christians simply do not know how to effectively express and defend their faith with people who have different beliefs.
But it doesn't have to be that way. The fact is, dealing with people who believe differently is not difficult at all if you know how to do it. This does not mean that you can merely read a book and everything is okay. If you want to be good at anything you have to put the effort into it to become good.
Now honestly, some things are not worth the effort it takes to do that. But when it comes to holding our own with our Christian faith, it is impossible to put too much effort into it. God has literally commissioned us to put a priority on sharing the gospel. This booklet is a great place to start. Here you will find the tools for arguing laid out nicely for you. From there, all you will need to do is pick them up and get good at using them.
