As Christ’s witnesses our perspective on life has been transformed by Christ’s rule in our hearts and informed by his Word, but those who do not yet know Christ, or whose faith is weak or troubled, naturally look at life from the viewpoint of the world. So we should expect to see these differences in our conversations and relationships. Nothing will close down a discussion about Christ more quickly than a Christian saying, “I’m right, and you’re wrong!” Instead see each conversation as an opportunity to build a bridge to the lost.
And in order to build a bridge you have to know both where you are coming from and where you are going so they can meet. That means putting yourself in the other person’s shoes and seeking to understand their objections and opinions. This doesn’t necessarily mean agreeing with them, it only means keeping the lines of communication open so that the gospel can be shared. You might say: "I'm sure a lot of people feel that way..." or “I used to think that way, too…” or “That’s an interesting observation…”
It’s hard to argue with anyone who cares enough to acknowledge your point of view and respects your feelings.
