When you experience both Silence and the Word deeply, you see that the Word comes from the Silence and the Silence is in the Word. When you really listen to God speaking to you in each moment, you see that what speaks to you is the Silence.
Angels are evidence that God is taking notice of us. They ask the same always: surrender, obedience, submission, and humility before the Holy One. Some say they make us homesick for heaven.
