Read: Matthew 7:15-20
Thus you will recognize them by their fruits. (Matthew 7:20 ESV)
All of my favorite fruits are quite frankly very easy to recognize. Strawberries are small, a deep shade of red, and distinctly shaped. Pineapples are characterized by their outer husk and pointy greenery. Watermelons are quickly noted for their green and often striped rind and round oblong shape. But the kind of vegetation a fruit comes from is not always so easy to identify unless you're an expert. The fruit itself is the key component.
The people who follow Jesus should be easily recognizable. We should readily, easily, and naturally demonstrate the kind of fruit that makes this a reality. Jesus said it himself. People are recognized for who they truly are by the kind of fruit their lives produce.
What kind of fruit are you demonstrating to an onlooking world? It's an important question. For way too long the American Christian community has been far too content simply answering the questions of life with grande theological responses. We spend too much time in our heads, or none at all. What our unchurched friends, family, and neighbors truly need to see is the evidence of Christian fruit.
