Many Christians do not share their faith with unbelievers simply out of fear. They’re afraid that the non-Christian will ask them a question or raise an objection that they can’t answer. And so they choose to remain silent and thus hide their light under a bushel, in disobedience to Christ’s command. Apologetics training is a tremendous boost to evangelism, for nothing inspires confidence and boldness more than knowing that one has good reasons for what one believes and good answers to the typical questions and objections that the unbeliever may raise. Sound training in apologetics is one of the keys to fearless evangelism. —William Lane Craig  (from, Christian Apologetics: Who Needs It?)
