The sole purpose of GMI is to evangelize lost peoples with methods changing from location to location. The major initiative is with Door to Door evangelism providing a New Testament Bible for each home. The teams work with volunteers trained through local churches who will follow up with ten lessons to build the faith of the recipient.
In Paraguay, there is a strong work in prison ministry targeting three prisons in Concepcion, Pedro Juan Caballaro, and San Pedro. In the Conception prison there is a church, a skills training centre, and a separate pavilion for the believers to keep them away from the challenges of the regular population where drugs are very accessible. This model is being duplicated in the other prisons.
A radio ministry has also just begun in Puerto Casado, Paraguay reaching the local area with the gospel message!
