Sharing with the Romans

I love being able to share Christ with folks that are struggling in their life and already know they are missing something. So many of them are ready and willing to hear the truth. I love planting seeds in this fertile soil that Jesus talked about in Matthew. I struggle, however, having the desire to go after the intellectual skeptic. I am nervous chasing after the person I know is going to try to pick my argument apart. I have complete confidence in my own faith, but will I be able to articulate it well to them? Will I be able to answer their questions effectively enough to win them over? What if they ask tough questions I am not equipped to answer?
