I once heard about a church that never uses the term "missionary." You will never hear, "This Sunday we're having a missionary as our speaker." They use the term "missions partner" instead. Nor do they ever use the term "missions pastor." They call him "pastor of missional living." I love that.
Don't get me wrong. I love and support full time professional missionaries. But every obedient follower of Jesus Christ is in full time missionary service. And we simply can't fulfil the Great Commission if we continue to outsource the work to professionals. They simply don't have the manpower to get the job done.
Just something to consider.
