All it takes is one spark to get a wildfire started.
Once that fire starts, it is nearly impossible to stop. The fire will roar loudly, burn hot, and reach incredibly high. It will be in one part of a forest one moment, and with the slightest brush of a breeze, it will jump whole acres to spread its flames and start a new blaze that will consume everything in its path.
That spark is the Lord, the fire is the evangelist, and the breeze thatdirects the fire is the Holy Spirit. This is what an evangelist is called to do. They are called to start a fire in the hearts and souls of both fellow believers and unbelievers alike that brings us into a reality of Christ.
