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.
Live your life so that the fear of death can never enter your heart. When you arise in the morning, give thanks for your food and the joy of living. And if perchance you see no reason for giving thanks, rest assured the fault is in yourself.
