I believe I know something that others should want to know, but telling is not a good way to get their attention.
What does he/she want to know? Why? What are the barriers to even considering the spiritual aspect of life? How do I help someone become interested in something he/she believes has no importance?
In writing, don’t insult the intelligence of the readers. They believe they have good and sufficient reasons for the way they believe. I have been where they are. What changed my way of seeing things? What made me want to see if I was missing something?
How can I take the reader along on that journey? What caught my interest, made me want to keep looking? When did doubts about the things I had always believed to be true begin to creep in? When did those doubts become stronger than my original beliefs?
What was the turning point, the climax of doubt, the need to find an answer?
It does not work to give someone the answer to a question that has never come to his mind. It didn’t work that way for me, why should I expect it to work with someone else? Sharing the gospel is not a matter of giving pat answers, but of asking questions–questions that will make others begin to ask their own questions.
Flatlander Faith 
A certain Holdeman minister was at a self serve filling station when a worldly young man pulls up and begins fueling his vehicle. The sound system was turned up and loudly playing his favorite rock music for al to hear , whether they wanted too or not.
It was somewhat annoying to the preacher and he thought to say something to the young man . He could have said many things to him about his satanic music and his disrespect for others etc. But instead he asked the young man a simple question. ” Do you like that music ” ? Enough said.
