In light of the coming Messianic Kingdom, the Church’s primary role is to acknowledge and worship God in his present benevolent sovereignty over all things in the heavens and on the earth, and to wait, hope and pray for the Day of the Lord and the coming of His Messiah.   

Secondarily, the Church is called to prepare for its inheritance in that kingdom. It is called to holiness and blamelessness that we might receive a rich welcome into the coming kingdom. This is the context of discipleship and sanctification, training to reign in love and righteousness.  

The tertiary role of the Church is to be a witness of that Kingdom—and the judgment and restoration therein—to all the nations.  - John P. Harrigan
