Note 3 at Acts 26:10: When debating an issue, one of the strongest arguments your opponent can offer is to say are biased or you don't know both sides of the issue. Paul is defusing that argument by recounting that he was stricter in Pharisaism than any of his accusers, even persecuting the followers of Jesus unto death. By bringing this up he showed that his accusers were the ones who were prejudiced. He had been on both sides of this issue.

When sharing our faith with others, it is beneficial to identify with the ones we are witnessing to if possible. This will let them know that we have had similar questions or doubts and that there is an answer. They will be more attentive.

However, just because we have not encountered the situation the person we are sharing with has, does not mean we cannot be effective in our witness. God's Word is their answer, not our experience. Relating similar incidents in our lives simply helps others to drop their barriers to receiving God's Word.
