What does the Bible say about the church's commission?

The church's commission is rooted in the Great Commission as described in Matthew 28, where Jesus instructs His disciples to go and make disciples of all nations. In John 20:21, Jesus says, 'As my Father hath sent me, even so send I you,' indicating that just as He was sent to fulfill God's plan of salvation, so are His followers to continue this work. This commission emphasizes the importance of proclaiming the gospel, which is the good news of salvation through Jesus Christ, to all creation, highlighting the authority granted by Christ to His church.
