O. L. Jaggers in A Man Sent From God
Thus is concluded the account as supplied from information given by those of Brother Branham’s congregation at Jeffersonville. We might also add that during those early months two young men by the names of O. L. Jaggers and Gayle Jackson attended a number of the services. Recently at a special conference in Dallas those two young men
asked Brother Branham if he remembered them. He did, but was greatly surprised that these brethren, who since have been blessed with amazing success, and whose ministries have reached tens of thousands for Christ, and have been attended with mighty signs and wonders, were the same young men who had come to his meetings in his early campaigns.
