Every Christian is called to be a witness for Christ. As a pastor or church leader, you are called to equip your church to fulfill the Great Commission. Your task is to mobilize every believer in your church to be a witness for Jesus Christ. But the statistics show that a growing number of Christians are simply not living with that mission in view.
The debate has been over for a long time. Word-of-mouth is by far the best way to get more visitors to your church. A church invite card given by someone in your church is better than any billboard or TV commercial.
