"Never a daisy grows but a mystery guides the growing." Richard Realf
I cannot know the author's thoughts, but I believe that God is the "mystery" guiding the growing. For does He not guide every growing thing? Including you and me?
The daisy grows with the perfection of one of God's creations. My own growth is far more erratic. I grow in fits and starts. I regress in the same fits and starts. If only I could pattern my growth after that of a daisy ...
This I know for sure: God's hand is everywhere, in everything. It is up to us to acknowledge it.
