The defining characteristic of a group of people who are living a shared life under the headship of Jesus Christ is love. Love for Christ, love for each other, love for the world. Not power or gifts. Not revelation or prophecy. Not service or missions. Believe it or not, you can have those things without love. However, if you have love, you have no need to worry about having those things. They will all come in their proper time and place.
There is no need for striving in discovering what it means to love and how to do it. We know who Love is. Just get to know Him who dwells within you and within your brothers and sisters.
