Written over half a century ago by two ladies, the "Two Listeners", who wished to remain anonymous, this has had proved one of the best selling devotional books of all time. With its companion volume, sales are well over 10 million copies worldwide.

Those who have suffered pain and worry know how hard it is to write of serenity within. The message of comfort and hope that breathes through the pages of God Calling was forged out of adversity, and as a result has touched the hearts of millions.

LAW OF SUPPLY
When supply seems to have failed, you must know that it has not done so. But you must look around to see what you can give away. Give away something.

The two authors were ladies with a deep Christian faith, one an Anglican, one a Roman Catholic, and retired school teachers. They were good friends of many years standing. They both developed cancer in the 1930s, and were in some distress. Inspired by a book they had been given called For Sinners Only by A. J. Russell, a London journalist, they began to practice what he suggested-the idea of listening to God in daily silence and jotting down the thoughts given to them at that time. They found the practice invaluable, and wrote to Mr Russell thanking him for his suggestion and enclosing some of the inspired thoughts given them.

Mr Russell took the next train to Birmingham, seeing this as a perfect example of the practice he recommended. He asked their permission to compile and edit a book using what God had given them. At his urging they finally agreed but did not wish their names to be used. The books were first published in England with an introduction by Mr Russell.

The copyright in the book was eventually passed to Arthur James Russell, who went on to found Arthur James Ltd. the authors died in the 1940s and late 1960s.
