After they arrived at Capernaum and settled in a house, Jesus asked his disciples, "What were you discussing out on the road?" But they didn't answer, because they had been arguing about which of them was the greatest. - Mark 9:33-34
It's embarrassing when someone demonstrates he or she can read your mind. Most of us would rather not have our thoughts exposed. We're not proud of our motives. We don't want our intentions broadcast. The disciples had a problem--Jesus understood them. Just as he understands us.
Every tactic we use in human relationships to avoid the truth is absolutely transparent to God. The fact that God
knows us that well isn't amazing. After all, he is God. The fact that we still try to work our magic on him isn't all that surprising either. After all, we are human. It is amazing though that God knows us as he does and still draws near to help us be better than we instinctively are.
The disciples were arguing about leadership. They were mind-wrestling over who could claim the top of the heap.
