Wouldn't it be nice to know for certain?
This peach tree knows it is not finished until it bears fruit.
As for the little sparrow it seems to always know when the bird seed is finished and it is time to go.
Hope each of you have a wonderful week.
"Thus the heavens and the earth were completed in all their vast array. By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work."
Genesis 2:1-2 (NIV)
