Upon accepting the Lord Jesus Christ as Savior, a believer becomes part of His body, which is the church. There is one church universal, composed of all those throughout the world who acknowledge Jesus Christ as Savior and Lord. The Scriptures command believers to gather in order to devote themselves to worship, prayer, teaching of the Word, observance of the ordinances (baptism and communion), fellowship, service to the body through the development and use of talents and gifts, and outreach to the world in fulfillment of the command of Christ to make disciples of all believers (Ephesians 5:23; Romans 12:1; Acts 2:42-46; 1 Corinthians 14:26; Matthew 28:18-20).
Wherever God’s people meet regularly in obedience to this command, there is the local expression of the church – under the oversight of elders and other supportive leadership. The church’s members are to work together in love and unity, intent on the ultimate purpose of glorifying Christ (Ephesians 4:16).
