Perhaps this one is not so much forgotten, just not sung in many churches as it is simply not included in most hymnals.
Tell The Blessed Story
Church of God, awaken; heed the Lords command,
Tell the blessèd story of the cross.
Fields are white for harvesting on every hand,
Tell the blessèd story of the cross.
(chorus)
Tell the blessèd story of the cross of Jesus,
Tell the blessèd story of the hallowed cross.
Until every nation learns of full salvation,
Tell the blessèd story of the cross.
Has not He commissioned you the news to bear?
Tell the blessèd story of the cross.
Go ye into all the world, and everywhere
Tell the blessèd story of the cross.
Stand no longer idle while the moments fly.
Tell the blessèd story of the cross.
Multitudes in heathen darkness live and die.
Tell the blessèd story of the cross.
Publish unto all the world redeeming grace.
Tell the blessèd story of the cross.
Until in the home of rest you find your place.
Tell the blessèd story of the cross.
If you do not know this one, go here, and give a listen to a fairly good midi of the song:
