The Apostles used to enter synagogues teaching and disputing against the opposition, however none of this was written. They preached in Jerusalem, Judea and Samaria until everyone believed, but only a little of what they preached was recorded in writing. The Apostle Paul entered a house in Rome where he stayed for two years preaching the kingdom of God and teaching about the Lord Jesus Christ boldly and without hindrance (Acts.28: 30,31). None of that preaching has reached us in a written form. Where did it all go?
