From Breaking the Missional Code: Your Church Can Become a Missionary in Your Community, by Ed Stetzer and David Putman
 A prayer walk is simply what it says: walking (or driving) through a community while praying for the people. Ask God to reveal things to you as you walk. Here are specific things to request:
  • Ask God to show you how to reach the people who live in the homes that you pass.
  • Ask God to prepare people's hearts to receive His Word and draw them to Jesus Christ.
  • Ask God to reveal a person of peace as you move around the area.
  • Ask God to help you understand how you can meet practical needs in the community and show the love of Christ.
As you do the prayer walk, God will begin to reveal other things about which to pray - both things to stand against and things to affirm. Make spiritual warfare part of your strategy. Pray that God might reveal what keeps local people from trusting in Jesus Christ, and then ask the Holy Spirit to break through those barriers. The history and industry of the community may also provide insight regarding spiritual strongholds.
