I think Sister Julian would have approved of the following!
It is difficult to speak of the aim or goal of [contemplative] prayer, for there is a sense in which it is a process of union which is as infinite as it is intimate... The meaning and design of the Jesus Prayer is an ever deepening union with God, within the communion of saints. It is personal, corporate and eternal, and the great mystics, in the Biblical tradition, come to an end of words. They say that "eye has not seen nor ear heard", they speak of "joy unspeakable" and "groanings unutterable" and "peace that passes understanding".
But there are some things which we can say, which are derivative of that central core of ineffable experience. We can say that such prayer contains within itself a new theology of intercession. It is not that we are continually naming names before God, and repeating stories of pain, suffering and bereavement on an individual and corporate level, but rather that we are able to carry the sorrows and pains of the world with us into such contemplative prayer as opens before us in the use of the Jesus Prayer. God knows, loves and understands more than we do, and he carries us into the dimension of contemplative prayer and love, and effects salvation, reconciliation and healing in his own way, using us as the instruments of his peace, pity and compassion.
Thus we can say that the "prayer of the heart" unites us with the whole order of creation, and imparts to us a cosmic awareness of the glory of God in both the beauty and the sadness of the world. The process of transfiguration for the whole world has begun in the Gospel, but it will not be completed until the coming of Christ in glory. And until that time we are invited, through prayer, to participate in the healing of the world's ills by the love of God. And if we participate at such a level, then we shall know both pain and glory. The life and ministry of Jesus in the gospels reveal this dimension, for Jesus was at one and the same time the "man of sorrows, acquainted with grief", and the transfigured healer, manifesting the glory of the Father upon the holy mountain.
