I think President Harrison, along with a gross number of other people who call themselves shepherds need to revisit simple Lutheran Doctrine. To many of these learned doctors of Scripture need to understand what exactly the LCMS historically considers to be the proper distinction between Law and Gospel.

The Gospel is indeed no system of ethics. It is the forgiveness of sins. That being the case, it should be noted that C.F.W. Walther said there is no good news for secure sinners, only the Law is to be preached to them (Thesis one, God's No, and God's Yes.) Simply put, people who are ok with the filth they roll around in are, well, you figure it out. However, people who are truly insecure need to embrace that forgiveness through repentance, and thereby cling to the promise of the Gospel. Knowledge of the Law leads us to understand what it is we should be terrified of (Rom. 7:7)

What President Harrison's message looks like to me is something out of John Calvin's book on Christian Doctrine. Once saved, always saved. God is no pushover, which unfortunately too many of us have forgotten.
