The Church's "mouth must be filled with the gospel."

Therefore if the Church is to fulfill its task on earth, its mouth must be filled with the Gospel, and it must be diligent to open that mouth wide. It must not allow itself, through want of success, to set aside the preaching of the Gospel in order to pursue other means. What cannot be redeemed through the Gospel certainly cannot be redeemed. Would to dear God that He preserve our Synod so that we let it be our proper task to proclaim the Gospel near and far. Then, for our part, we will we assist in gathering the scattered children of God and preparing them for the kingdom that has been prepared for them from the foundation of the world.
