Prayer obtains what it is due to obtain — not what I personally want to obtain, which is different. It is useful that islands of prayer exist in the world, even if they are composed of only one person, or two, or three, or four.
Deeply spiritual persons experience the suffering in the world as their own suffering. Their skin is like a dividing membrane through which events flow into each other. But they do not let it overtake them and destroy their spirit, their ability to choose life. To live deeply in the spirit is to be able to see beyond the immediate evidence of brokenness. It is to seek the not yet, but possible future. To live deeply in the spirit is to find the courage to create in the midst of darkness.
