The Church doesn’t exist in order to provide a place where people can pursue their private individual spiritual agendas and develop their own spiritual potential. Nor does it exist to provide a safe haven for people to hide from the wicked world and ensure that they themselves arrive safely to a heavenly destination.
The New Testament seems pretty clear that through the Church God will announce to the wider world that He is indeed its wise, loving, and just Creator. And that through Jesus He has defeated the powers that enslave it. And that by His Spirit He is at work to heal it.
The Church exists, in other words, for what we sometimes call “mission:” to announce to the world that Jesus is Lord. This is the “good news,” and when it’s announced it transforms people and cultures.
