Acts 26

Paul made his case to King Agrippa, boldly making a case for Christ at the same time. He appealed to Agrippa's knowledge of Jewish customs as the basis to judge what he was saying. Agrippa was convinced that Paul had done nothing wrong and would have set him free except that Paul had appealed the matter to Caesar.

When witnessing for Jesus, it is important to know the background of the person you're talking to. Start by finding common ground and showing where there is already agreement. Then, build on those things and show how Jesus fits right in with those truths. By doing this, most people become much more willing to listen because they don't feel that they have to defend their position.
