What should be the mission of the church?

The church is a creation of God (See Acts 20:28;
1 Corinthians 3:9, 17;
15:9), founded and owned by Jesus Christ, “I
will build my church…” (Matthew 16:18), and
directed and energized by the Holy Spirit. (See 1 Corinthians
10:17; 12:5–27; Romans 12:4–5) Therefore, it is the church’s
joy to look to God to explain His design for the church and His mission for it.
 

God’s mission for the church proves to have several parts:

1) The
mission of the church is to make disciples.

Just before Jesus returned to heaven, He commissioned His disciples
this way, “Therefore go and make disciples of all nations, baptizing them in
the name of the Father and of the Son and of the Holy Spirit, and teaching them
to obey everything I have commanded you. And surely I am with you always, to
the very end of the age.” (Matthew 28:19–20)

A disciple is a follower, someone who attaches himself to his
leader.  Jesus sent the church on its
mission to acquaint people in every place with Himself.  As the church makes disciples, people can
admire, worship, trust, follow, and obey Jesus as their Savior and Lord.  The church’s members assemble around Him as
Master, Leader, Savior, and Friend.  Our mission
is to reflect Christ to every nation.

2) The
mission of the church is to glorify Christ.

Paul wrote, “In him we were also chosen…in order that we…might
be for the praise of his glory.” (Ephesians
1:11–12)  Part of God’s
purpose for the church is to exalt Jesus Christ by the way that the church
lives and by what it does.  Christ
designed His church to represent His supernatural, life-saving work to the
world.

In His church, Christ shows to the world what a freed and forgiven
people are like, people who are satisfied with God as the result of Christ’s
joyful and victorious self-sacrifice.  He
has planned the church’s values to be His values.  He expects its lifestyle to reflect His
character. (See 2 Corinthians 6:14—7:1;
Ephesians 5:23–32; Colossians
1:13, 18;
1 Timothy 3:15)  As the moon reflects the sun, so the church is
to reflect the glory of God to a dark world.

3) The
mission of the church is to build up the saints.

The church is to encourage and comfort its individual members. (See
1 Thessalonians 5:11; 2 Corinthians 13:11)  “…so that there should be no division in
the body, but that its parts should have equal concern for each other.” (1 Corinthians 12:25)  Jesus is the chief cornerstone,
and the church is likened to a building “…joined together and rises to
become a holy temple in the Lord. And in him you too are being built together
to become a dwelling in which God lives by his Spirit.” (Ephesians 2:20–22)

Jesus Christ designed His Church to showcase God’s family on earth,
so that the pagan world can see how God builds His family around Jesus Christ
and how that family cares for one another. (See Mark 3:35)  The mission of the church is to know and love
Christ so completely as to represent Him and His values accurately and vividly
to the world, and serve people’s deepest needs in the way Christ Himself would
meet them.

As W. C. Robinson says in Baker’s Dictionary of Theology, “Our
Lord Jesus Christ is the sun about which the whole mission of the church
revolves. Public worship is the encounter of the risen Redeemer with His
people; evangelism is calling men to the Savior; publishing the law of God is
proclaiming His lordship; Christian nurture is feeding His lambs and
disciplining His flock; ministering to the needs of men is continuing the work
of the Great Physician.”  

The church’s mission is to present Jesus Christ to the world, while
He presents to the same world His rescuing work in and through His church.
