Proof!

John15:25 But the word that is written in their Law must be fulfilled: ‘They hated me without a cause.’ [ESV]

The reference to “is written in their Law” without a footnoted citation left me searching commentaries to unravel the obscurity of that phrase.  Here are some notes I made searching for clarity that became my food for thought.
• Jesus as command-giver vs mankind as command-keepers
• fulfilling the law through merit or mercy
• divine destiny
• finally this quote from an obscure commentary by Philip Schaff ^a “The very law of which the Jews boasted, and into which, from imagined reverence for it, they were continually searching,—in that very law they might see themselves. In such a connection of thought might it not he [Jesus] be called ‘their law’?”

√ The first note I checked off without question was, of course, the divine destiny of Jesus.  That is a foundational tenet of our faith as Christians.
√ Then I went on to considering the difficulty of yielding to a command-giver when you’re a command-keeper living in a highly merit-based system.  That is a foundational dilemma of human nature.
√ Finally the quote from Schaff reminded me of this foundational truth from Jesus himself in Matthew 5:17
“Don’t misunderstand why I have come. I did not come to abolish the law of Moses or the writings of the prophets. No, I came to accomplish their purpose. 18 I tell you the truth, until heaven and earth disappear, not even the smallest detail of God’s law will disappear until its purpose is achieved.” [NLT]
√ Proof: ‘They hated [Jesus] without a cause.’
