"What is the basis of our security? When we start thinking about that question, we may give many answers: success, money, friends, property, popularity, family, connections, insurance, and so on. We may not always think that any of these forms the basis of our security, but our actions or feelings may tell us otherwise. When we start losing our money, our friends, or our popularity, our anxiety often reveals how deeply our sense of security is rooted in these things.
A spiritual life is a life in which our security is based not in any created things, good as they may be, but in God, who is everlasting love. We probably will never be completely free from our attachment to the temporal world, but if we want to live in that world in a truly free way, we'd better not belong to it. "You cannot be the slave both of God and of money" (Luke 16:13)." Henri Nouwen
