Jesus’ mission, as prophesied by Isaiah, is given in Luke 4:18-19:

The Spirit of the LORD is upon Me, because He has appointed Me to preach the gospel to the poor; He has sent Me to heal the brokenhearted, to proclaim liberty to the captives and recovery of sight to the blind, to set at liberty those who are oppressed; to proclaim the acceptable year of the LORD.

We believe that as the Church is the body of Christ (1 Cor 12:27), we are to continue this mission under the guidance of the Holy Spirit (John 16:13), in the power of Christ (1 Cor 1:24), and all for the glory of God.
