The Kingdom is NOT the Church

For many years now (most of the 20th century), the Churches of Christ have been teaching that the kingdom is the church--that they are one in the same. Yet it seems to me that the way Jesus talks about the kingdom does not fit with how Paul and Luke and others talk about the church.

The kingdom appears to be the mysterious work and will of God at work in the world. The church appears to be the people who want to be vessels of God's will in the world--we are the vessels through which the kingdom can come and reign.

The kingdom comes, when God's will is done.
The kingdom is present, but not fully present. It is growing.
The kingdom is already here, but it is not yet fully here.
The church is part of the kingdom, but it is not THE kingdom.

But I want to hear from you on this. What do you think? What have you heard and been taught? What Scriptures could we shine on this subject?

Share your thoughts for the sake of truth...in love.
Peace.
