Hi John! I love what you have written, specifically about being able to have “an openness to accept fault and a desire to change your opinion.” The second we as Christians believe that every single little detail of theology we hold is correct against another Christian’s viewpoint is when we start to struggle with pride and have more head knowledge. Having more head knowledge can definitely take two directions: one that completely misses the Gospel, the love of Jesus, and the cross or one that allows their knowledge to take them deeper into the Word.
