We are called to have unity but still be individuals in our purpose, calling and gifts. These gifts are for a distinct purpose from the Lord however WE should not be our main focus. He brought us together not for ourselves, but for the greater glory of Him, and to impact the lost world around us. This sometimes pushes us out of our comfort zone, like when iron sharpens iron. We have the tendency to stay away from this because of the friction it creates, but it is so needed.
