This is Dr. Wierwille’s Sunday Night Service Tape 809, first recorded in May of 1976, two years before I decided to believe the Bible. Many things Dr. Wierwille states in a general way are the great truths of II Corinthians chapters three, four, and five.
The text linked to the harvest above goes through every use of we in II Corinthians chapters one through seven.
Working through these uses reveals that II Corinthians 1-7 is the greatest revelation of evangelistic truth ever given to the church.
Linked to this photo of the Teacher is his Dr. Wierwille's foundational teaching on the great realities of II Corinthians chapters one through seven.
