Are You A Witness?

Here in Florida, one of the most frequent announcements on the television comes from Crimestoppers. The police are always appealing for people who have witnessed a crime to come forward and testify. If you are ever involved in  an accident or some other situation that would warrant a court appearance, you would need a witness. To me, these things sound very unpleasant, and I thank God that I've never been a witness or needed a witness to testify on my behalf. However, the Bible does call on us as Christians to be witnesses.
