This is an article by William Lane Craig, I erge you to read it, and use the website itself = ). If you need more I'll post them. My purpose for this guild is a rest, and a place where one can gain more knowledge of Christianity, so that you can keep witnessing and teaching the name of Christ, '14How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher? 15And how shall they preach, except they be cent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!'-Romans 10:14, 15
