Quotes:

"Some may find them merely diverting melodies. Others may find them incitements to Red revolution. And who will say if either or both is wrong? Not I."

Realize that little things lead to bigger things. That's what Seeds is all about. And this wonderful parable in the New Testament: the sower scatters seeds. Some seeds fall in the pathway and get stamped on, and they don't grow. Some fall on the rocks, and they don't grow. But some seeds fall on fallow ground, and they grow and multiply a thousand fold. Who knows where some good little thing that you've done may bring results years later that you never dreamed of?
