A: One way is to ask a question. Dialogue is sort of like ping-pong. One person serves (starts the conversation) and what ensues is a lobbing back and forth (the give and take of conversation). Now, the best way to start a conversation on any subject, be it music, sports, or God, is to ask a question. It's best to ask an open ended question. An open ended question is one that cannot be answered yes or no. It requires a more thoughtful response and will stimulate conversation and encourage deep thinking. A question about where someone attends worship or what their beliefs on God are can be great ways to get your foot in the door. However, not only do you want to be able to ask questions, you want to answer them. If you are a true Christian and you are living the life you should, you will stand out. People will notice and ask you about your peculiar life style. However, a lot of Christians will shy away from these sorts of encounters out of fear of coming across as "holier than thou", or something to that affect. What they are failing to see is that they have been handed an invitation to study with someone. If a friend or family member asks you about your faith, you don't have to worry about getting your foot in the door because the door is standing wide open at that point. Take advantage of these opportunities. I would also suggest getting them involved in activities at your local congregation. This is as simple as inviting them to a Sunday morning service or asking them to attend a youth devotional. From there, you can simply ask "What did you think of the lesson?".
