There are many different kinds of prayer. Yet all prayer has one basic purpose. We pray not to get something, but to open up a two-way street between us and God so that we (and others) may inwardly become something beautiful that we share with others.
The experience of prayer is the experience of coming into full union with the energy that created the universe. What Christianity has to proclaim to the world is that that energy is LOVE and it is the well-spring out of which all creation flows. It is the well-spring that gives each one of us the creative power to be the person we are called to be -- a person rooted and formed in love.
