Yes, we are a community of believers (1 Peter 2:9)--one body with many different parts linked together with no one part being more important than another (1 Corinthians 12). We are linked together by our belief that Jesus Christ is the son of God who came to live and die for the forgiveness of our sins. Who we are to each other is clear.
As followers of Christ, we are all called to go into the world to all people . . . to baptize them in the name of the Father, Son, and Holy Spirit . . . and to teach them to obey everything that Christ commanded (Matthew 28:19-20). Our mission is clear.
Our power for this awesome task comes from the Holy Spirit, whom Christ sent to dwell within us (John 14:15-21). Our love for Christ will be revealed to the world through our good works. We are to care for those who cannot take care of themselves and those who are victimized by others (Luke 4:18). Our power source is clear.
Church is a spiritual, living, breathing, growing social organism not just a building (Ephesians 4:11-16). We are God's peple . . . we are a community of believers . . . we are Marvin united with other Christians throughout the world.
