Roundtable 6 is up at the Concordia: The Lutheran Confessions blog, and the topic is Article V. It is an excellent post, and the comments are equally worth reading. My favorite part of their post:

But how does one receive such faith? Faith does not concern itself with “finding Jesus” by somehow traveling backward through time to the historical event of Jesus’ crucifixion. Salvation was achieved on the cross at Calvary, but it was not delivered there. The “instruments” extolled in AC V (Word and Sacraments) deliver salvation, but do not accomplish it.
