Jurgen Moltmann writes:
For me, children are metaphors of hope for three reasons:
(1) With every child, a new life begins, original, unique, incomparable. And while it seems that we always ask, who this or that child looks like (apparently because we seem to think we can only understand the new in the comparison with what is already known or similar), we also encounter the entirely different, the entirely dissimilar and unique in each child. It is these differences that we need to respect if we want to love life and allow an open future.
(2) With every beginning of a new life, the hope for the reign of peace and justice is given a new chance. It is important to see children in their own transcendent perspective and so to resist forming them according to the images of our world. Every new life is also a new beginning of hope for a homeland in this unredeemed world. If it were not, we would have no reason to expect anything new from a beginning.
(3) The last reason to see “a new beginning” or a “beginning of the New” in the beginning of a child’s life is the fact that, for me, children are not only metaphors of our hopes, of that which we want, wish for and expect, but also are metaphors of God’s hope for us: God wants us, expects us, and welcomes us. Humanity is God’s great love, God’s dream for God’s earthly world, God’s image for God’s beloved earth. God is “waiting” for the “human person” in every child, is “waiting” for God’s echo, resonance, and rainbow. Maybe that is the reason God is so patient with us, bearing the ruins of human history, inviting one human generation after the other into existence. God is not silent, God is not “dead”—God is waiting for the menschlichen Menschen the “truly humane human.” “In all of the prophets, I have waited for you,” Martin Buber has the Eternal One speak to the Messiah, “and now you have come.”
With this kind of transcendental expectation placed on every newborn child, it becomes the task of parents, siblings, and teachers to hold open the doors to this future and to walk with these children into this future.
