God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
Since the conscience holds people to their highest perceived standard, believers need to set that standard to the highest level by submitting to all of God’s Word. As they continually fill their minds with the truths of Scripture, believers clarify God’s perfect law. Their consciences will then call them to live according to that law.
The holiest moment of the church service is the moment when God's people – strengthened by preaching and sacrament – go out of the church door into the world to be the church. We don't go to church, we are the church (Ernest Southcott).
