Just so we are clear about this...
It is not we who build. (Christ) builds the church. No man builds the church but Christ alone.
We must confess - He builds. We must proclaim - He builds. We must pray to Him - He builds.
Church - stay a church! But church, confess, confess, confess! Christ alone is your Lord; from His grace alone can you live as you are. Christ builds.
Dietrich Bonhoeffer, from "Treasury of Daily Prayer," page 841
