This blurb of mine was published recently in Connections magazine
Trees have evolved a clever way of making sure their seed gets distributed far and wide - fruit! The fruit attracts animals which carry it off, eat it and leave the seed within behind to take root and grow. A tree doesn't grow fruit for its own use, but to entice others to grab hold of it and carry the seed off with them. Just so, the fruit that believers bear is not meant for themselves but for the nourishment of others that they too may take the seed within (the Word!) and carry it far and wide.
