NOTES for Luk 21:33
Strange, is it not? We are used to the idea that heaven and earth, this whole world, the whole universe, are something real, something one can see and show to another, something obviously existing. But words are ephemeral: they sounded and are gone, flew out and flew away. "Words, words, words..."
But Jesus, as always, overturns everything. The Word, when it proceeds from God or from the God-man, is not ephemeral; it is more real than any material reality, because it was precisely by the word that this world was brought into existence. The world is created, and therefore it is not eternal; it has a beginning and an end. But God's word is not created; it is begotten by the Eternal God. It has an eternal nature, does not disappear, and does not remain fruitless.
This means that for us, who belong to the created world, in order not to pass away with it but to enter eternal life, we need to seek God's word, listen closely to it, receive it, become permeated by it, becoming like Christ, the Word Incarnate.
