Most churches have some sort of vision/mission statement. They may have both. But more is needed than just having a vision statement. Even having the vision posted on the wall is not enough.
It is the pastor’s job to put the vision in front of the church as often as possible. It is more than just reading the statement or putting it in the bulletin.
One of the things that I do is to plan sermons connected to our mission. I also organize our bulletin under the four headings that comprise our mission statement. I have also planned out to take a year to focus on each of those four components of our mission. This gives me time to invest in each aspect and make sure our church is living out our mission.
One resource that I would recommend is Making Vision Stick by Andy Stanley.
