This picture of Dan Beyer at the Super Bowl in Minneapolis represents one goal of the ministry and that is to be at the gates of the event if possible and to be a reminder to the fans of the Gospel.
In this picture Dan is using a sign and is preaching. Members of another team are on the corner evangelizing. So as the fan would pass that team Dan would be the final sign of the Gospel for the fan.
Keep in mind that Dan and the team would have bene evangelizing for three days to the fans and as the fans go into the stadium many would have already seen and heard the Gospel perhaps multiple times.
Our job is fulfilled in our constant vigilance to fans.
