As a Christian, I am familiar with the Gospels and their accounts of Christ’s life. I’ve read each several times and feel I know them pretty well. At the behest of a friend, I started reading John four days ago. To mix things up, I have been reading aloud (I feel the reading experience is much improved when the auditory senses are also engaged).
To that end, I’ve always been slightly disappointed that the writers of the gospel seem to make Jesus’ words easily understandable (to say nothing to Biblical translations that trade beautiful poetry for accuracy in modern language). However, John has been a relief from that. John seems to have maintained the intelligence and the poetry with which Christ taught. When confronted by the Pharisees, Jesus not only teaches them true doctrine, but does so in a convincing, intelligent way. He leaves no room for misunderstanding nor argument. He is the master teacher.
I guess the point is I am grateful for intelligent argument in defense of Truth. Too often I find people that say, “I know it’s true. That’s enough for me.” In recording Jesus’ full defense f His actions, John wants to raise the reader to a higher level: he wants us to know why we believe what we do and why Jesus’ teachings are correct.
