Extending this to you and all others it means that should you (or they) never take another person shopping, never make another person smile, never use the gift you are in any way except to allow the God who is faithfulness itself to be faithful to you, THAT is the hiddenness and the gift I am mainly talking about. Yes, it involves the hiddenness of God at work in us but that is the very reason we are gift. We witness to the presence of God in the silence of solitude, in the darkness, in the depths of aloneness, etc. We do that by becoming whole, by becoming loving (something that requires an Other to love us and call us to love), by not going off the rails in solitude and by not becoming narcissists or unbalanced cynics merely turned in on self and dissipated in distraction. We do it by relating to God, by allowing God to be God.
As I noted here recently, I once thought contemplative life and especially eremitic life was a waste and incredibly selfish. For those authentic hermits the Church professes and consecrates, and for those authentic lay hermits who live in a hiddenness only God can and does make sense of, the very thing that made this life look selfish to me is its gift or charism. It is the solitude of the hermit's life, the absence of others, and even her inability to minister actively to others or use her gifts which God transforms into an ultimate gift. Of course, in coming to understand this, it is terribly important that we see the "I" of the hermit as the "We" symbolized by the term "the silence of solitude". It is equally important that we never profess anyone who does not thrive as a human being in this very specific environment. In other words, my life, I think, is meant to witness starkly and exclusively to the God who makes of an entirely impoverished "me" a sacramental "We" when I could do nothing at all but allow this to be done in me.
