Geof has created extensive teachings on 17 Books of the Bible, and completed 16 Studies on major Bible themes including Salvation, the Work of Jesus Christ, the Ministry of the Holy Spirit and Church Government. He continues to serve his church in both teaching and pastoral care ministry and is also in popular demand as an international professor for the Texas University of Theology of Hurst, TX.
