The 16th century Spanish mystic, Saint Teresa of Avila said:
Christ has no body now on earth but yours,
no hands but yours,
no feet but yours,
yours are the eyes through which Christ's compassion
is to look out to the earth,
yours are the feet by which He is to go about doing good
and yours are the hands by which He is to bless us now.
I love this thought for several reasons, it reinforces the concept that all of us are important and have a purpose. We may not see it at first or may question why we have to go through the problems we endure, but we can be a lighthouse to those tossed about in similar situations. We may be the only light that some people see, and how we handle our storms gives others hope and guidance in their situation.
