Challenged to enlist

I have been extremely challenged by Ray Comfort and Kirk Cameron via their website wayofthemaster.com. I've known about Ray for quite awhile having heard about his ministry as a street preacher in LA. Somehow when Kirk became a Christian he got into the same ministry and they developed training videos on witnessing that I've been watching. These guys are very direct yet gracious in their approach. They have filmed people being "interviewed" in the videos and nearly all confess that they are a lying, thieving, blasphemous murderer and alulterer at heart and deserve hell from a just God. At no point is the incident confrontational or acrimonius. Both witnesser and witnessee are cordial and logical through the entire encounter. I used to be very active in furthering the kingdom of God but have been lax for many years now. I hope to report a resurgence in this area. To give you an idea of the mindset of these guys I give you a quote from C.T. Studd that they use.

"We Christians too often substitute prayer for playing the game. Prayer is good; but when used as a substitute for obedience, it is nothing but a blatant hypocrisy, a despicable Pharisaism. To your knees man! And to your Bible! Don't hedge! Time flies! Cease your insults to God. Quit consulting flesh and blood. Stop your lame lying and cowardly excuses. Enlist!"
