The 1967 Wabanna conference featured messages by DeVern Fromke, John Kennedy, Stephen Kaung, and T. Austin-Sparks. DeVern Fromke spoke about King David, John Kennedy spoke on prayer, Stephen Kaung on fullness, and Brother Sparks on the Cross.
According to Stephen, he and brother Sparks arrived at the conference prepared to speak on the same topic. He did not tell me which one of them changed their messages.
