This has been going on from the beginning. Remember the 2nd chapter where Jesus ran off the money changers; he upset their applecart, and the “Jews” had it in for him thereafter. (The synoptics put that scene near the end of their gospels.) The “words of Jesus” seem more like theological statements than the kind of conversation we find in the other gospels.
We remember Nicodemus from the 3rd chapter “born again” discussion (that was a ‘theological statement’ I could surely relate to). Nic represents those who would follow Jesus, but they’re on a materialistic mindset– like the majority of ‘Christians’ today! He was also a rich man, able to sit in the ‘seats of the mighty’.
Nic made a reasonable statement: shouldn’t we try this man before finding him guilty? This confounded the conspirators, nipped the conspiracy in the bud (temporarily), “And every man went unto his own house.”
We find Nic again with Joseph of Arimathaea asking for the Lord’s body. Here’s a quote from Peloubet’s Bible Dictionary: “In Nicodemus a noble candor and a simple love of truth shine out in the midst of hesitation and fear of man.”
