More about seeds - and genuine hope. From Paul Tillich:
"...there are many things and events in which we can see a reason for genuine hope, namely, the seed-like presence of that which is hoped for. In the seed of a tree, stem and leaves are already present, and this gives us the right to sow the seed in hope for the fruit. We have no assurance that it will develop. But our hope is genuine. There is a presence, a beginning of what is hoped for. And so it is with the child and our hope for his maturing; we hope, because maturing has already begun, but we don't know how far it will go. We hope for the fulfillment of our work, often against hope, because it is already in us as vision and driving force. We hope for a lasting love, because we feel the power of this love present. But it is hope, not certainty."
