There are several failures mentioned in the Bible.
There is the case of the "fig tree" that never bore any figs.
There were the "lamps without oil," the lamps that gave no light to the Virgins who held them.
There was the case of a watchman who was blind.
And there were "wells without water."
There are boys and girls now running about and enjoying themselves. Having a good time, and only thinking of pleasing themselves.
They are fruit trees in God's garden. Yet so far they have never brought Him fruit, though He comes again and again so patiently and lovingly, to see if there is any sign or beginning of fruit bearing.
They are lamps made to shine for their Master, but no light comes from them. They are useless.
They are wanted to be watchmen for God, looking out for the coming of their Master, telling others about Him and warning them of danger when it comes. But they see nothing. They are blind.
They are wells. Made by God to contain the Water of Life, and to be the means of refreshing and watering others. But they are dry and empty, or filled with rubbish, choked with refuse—and not a drop of water in them.
