I've recently read David Wilkinsons book, "The Cross and the Switchblade." The Lord really used that book to rekindle my burden for young people and to remind me of the power of the Gospel to change lives. (please note: I'm not in agreement with charismatic theology or a second work of grace.) If you are unfamiliar with that title, it is the story of a country preacher in PA used of God to reach the gangs in NYC.
I was interested in reading it because of how many times in my evangelism I have met people who have accepted Christ after reading that book.
I purchased five more copies of it to share with friends in our community. I handed out three of these yesterday. They were very well received. God is at work. Please pray for God to finish His great work in these hearts.
