L'Abri is the French word for "shelter". L'Abri fellowships are places where people - Christian and non-Christian - can come to ask honest questions about the deep questions of life, and hear honest answers from an honestly Biblical Christian perspective. The movement began in Switzerland in 1955, in the home of Francis and Edith Schaeffer. It's now an international ministry.
The fellowship have put their lecture library online for free download. Hours and hours of stimulating material on everything from art to sex to the nature of reality to what it means to be human to... well, everything! Tolle, audio! (Take, listen!)
