"The reason we must send them in a manner worthy of God is that they go out for the sake of the name. The name of God is at stake in how we treat our missionaries. God is glorified when we support them substantially with our prayers, our money, our time and myriad other practical ways. God is not glorified when our missionaries are simply a name on the back of a church bulletin or a line item in the budget." Tom Stellar in the Afterward of Let the Nations be Glad
Tom Stellar summarized well for my why we gather to pray every month. We want to be a sending church that supports our workers around the world. Praying is the most important and powerful thing we can do. Period. When we pray God responds. When we pray for those around the world, God moves. Prayer supports our workers in a special and unique way that they appreciate so much. If you don't know anyone in the field, find out someone who is and begin praying for them.
