You know the feeling. . . a song worm.   There are tunes and words that get into your head and no matter how you try, you just can't get them out?   This song from my childhood camp days came into my head a week as go as we studied John 12 in our Monday night Bible study.   It reminded me again that often we are discouraged because we are beset by storms in our lives, but at the same time God can use those storms to grow something for His kindgom.   And no matter how fruitless a task may seem to be, if God blesses it, is for greater glory.  

I hope this song blesses you.  If you go to the link at the bottom of the page, you can hear the tune that goes with it. . . and you, too, will have a song worm in your head.   (Let's hear it for helminthology!!!)

Kristian Ostergaard (1855-1931) (Den Sag er aldrig i Verden tabt); translated from Danish to English byJens C. Aaberg (1877-1970)

That cause can never be lost nor stayed
Which takes the course of what God has made;
And is not trusting in walls and towers,
But slowly growing from seeds to flowers.

Each noble service that men have wrought
Was first conceived as a fruitful thought;
Each worthy cause with a future glorious
By quietly growing becomes victorious.

Thereby itself like a tree it shows:
That high it reaches, as deep it grows;
And when the storms are its branches shaking,
It deeper root in the soil is taking.

Be then no more by a storm dismayed,
For by it the full grown seeds are laid;
And though the tree by its might it shatters,
What then, if thousands of seeds it scatters?
