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.
Meister Eckhart tells us that in silence we make room in our soul for God and that God delights to be in our soul when we have made room. Should we not then be building mansions of silence in our souls to welcome Love's Holy Presence.
