Prayer is getting in touch with reality, letting it speak in us, and incarnating the word which comes to us. We let it happen in our lives. Saying yes to God in prayer . . . means changing our lives in accordance with what we have heard. It means engaging that word with our whole being, and letting it alter our existence. For prayer is a dialogue between life and life, between divine life and human life, between life of the Spirit, and the life of the flesh. Unless we enflesh the work of God and let it become incarnate in us, it cannot become real in the world.
