Arminian,
Thanks for the concession
Now, if you read the passage, you would see that Jesus cleansed the temple, then Nicodemus came to him to try and shoot him down. Jesus, by cleansing the Temple was claiming to be more than just a Rabbi. WAY more. You couldnt probably read a claim to divinity, however Johns mention of the verse regarding 'zeal for His house' is a direct Messianic link. This action was a demonstration of Jesus claim to be the Messiah, the annointed King. Nicodemus recognised that, and came with the intention of proving Jesus wrong, although in a polite and respectful way.
He was unable to prove Jesus wrong, because the argument Jesus gave him was irrefutable. In the end Nicodemus has to admit Jesus is right: John 3:9 Nicode'mus said to him, "How can this be?" -
(incidentally, this is where the conversation shifts, Jesus begins to redirect the focus from Nicodemus to the crowd surrounding using you (singular( and you (plural)).
Nicodemus should understand, He should know what Jesus authority to cleanse the temple was, if He was really a Son of Abraham he would have recognised him as the Messiah.
See, Johns gospel was written to reveal Jesus as the Son of God, the Messiah, so that we might believe and have eternal life (john 20:31f)
He does this by having Jesus meet various characters, and reveal himself to them by words, signs, and wonders. Many of Jesus' discussions take on new significance when looked at in this light. Especially this one. Jesus' logic is so completely clear and true they cant defeat him.... just look at the buffoons in John 8:30-59. Jesus totally shoots them down... they call him a liar but cant convict him of any sin, so all the can do is call him names and try and kill him.
Fascinating stuff... I have been studying John's gospel for 4 years now.. with a passion. I looooove it. John, Gen 1-11, and the Psalter... thats where you'll find me...
