BibleGateway.com for all of the places “one another” shows up in the epistles. There is a lot of books, tests, workshops, videos, messages… on spiritual gifts, the key passages are Romans 12, 1 Corinthians 12, and Ephesians 4.

To what end? Essentially, based on the final command of Christ in Matthew 28:18-20, world domination. The community is to aggressively take His message and reproduce it by raising up disciples throughout the world. So the community is more of a huddle between plays where the team regroups rather than a restaurant or a mall to pick and choose ones purchase. Those from the church in Jerusalem turned the world upside down (Acts 17:6 NKJV).
What is your community like? Is it engaging your gifts and fanning your passion to follow and serve Christ by reaching your world? If not how are you engaged in changing that?
