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.
If we are committed in our lives to the force of lovingkindness, then people know that they can trust us. We will not deceive them; we will not harm them. By being a beacon of trustworthiness in this world, we become a safe haven for others. We become a good friend to people, and can experience the JOY of intimacy with life.
