Promote the ministry in your church bulletin. Use an "ad" to generate interest with church members. Sample bulletin ad.

Have a sign up sheet posted in a prominent location for interested members to join the ministry efforts. Sample sign-up sheet.

Every  inmate participating in this program will  fill out an application. The personal information allows the director to match each applicant with a spiritual church mentor. The church pen pal then receives the inmate pen pal's application to get to know her, her spiritual needs and prayer requests.    Sample inmate application.
