Isaac's life was a testament to his Habakkuk-like faith. He explored the world of culture; indeed, he reveled in it. At the same time, he celebrated both the mercy and justice of God. As we who mourn Isaac remember him, it is comforting to reread his words: "And lastly, nothing could express simple, stubborn confidence in the future better than Habakkuk's final brief professional note, 'For the Choirmaster. With my string-music.'"
Isaac is now with the Choirmaster. May the string-music of his memory never stop singing to us all.
