No, there are many non-faith based organizations doing God's work.....they just don't know it.
Persecution will find me soon enough....I don't need to go looking for it.
Years ago I attended OSU and one summer a preacher and his "entourage" set up a tent on the Oval and they began to preach. From what I do remember was they did preach the Word. What troubled me was the way it was preached. It was done in a clownish way, in a way certain to draw ridicule, curses, laughter, derision, etc.....At first I wondered why they did that and then slowly I could see that they reveled in it....they fed off of it....they desired it.....because it meant they were being persecuted......and is that not what happens to Christians? But they went looking for persecution, they sought it out,....I still wonder if God honors them for that....What I am trying to say, I guess, is don't be like them. Persecution is coming, don't go looking for it; it will find you soon enough.
