Spiritual condition: Born again. One of us in 1972 and the other in 1985.
Age: I was born in 1947. My wife, who assisted me on many of the teachings was born in 1953.
Education: What was the educational level of some of the Bible writers? There was a king, a medical physician, a highly educated religious expert, a tax collector, a fisherman, and a jailbird to mention a few. All were qualified to teach and preach the gospel of Christ. If the Holy Ghost quickens these teachings to your spirit, then you will profit from them. If not, then your gain will be more limited.
