Last week I met a Lutheran missionary to the Chinese-speaking people in Los Angeles. He said something that made me think. Doctrine comes later. First, they must see the love of Jesus through you. Then, they will believe what you say.
Empire builders are concerned with numbers.
Kingdom builders are concerned with showing and telling the love of Jesus, no matter what the cost. Empire builders see a person as a prospect for membership. Kingdom builders see a candidate for baptism. Empire builders look for growth opportunities. Kingdom builders look for opportunities to spread the good news of Jesus.
