Have you been through the Terrified series by Wretched?!!
They are seriously awesome.
Mr. Friel has an amazing sense of humor, and he mixes it in with the tools
that Christians need to confidently share our faith.
I loved listening to these, and our family listened to them several times,
along with the Herman Who? series of lectures (also put out by Wretched).
Basically, if you listen to them, and then apply what you hear (there's the rub)
you will, with much prayer and a righteous heart, be able to share our
faith with the people who frighten the wits out of you.
Hence the clever title, Terrified.
