The Egg is the story of a memory that took Roy and Anne Porter on a journey to Switzerland in order to become part of a ministry that would see thousands of children and young people and indeed many adults come to faith in Christ. The egg was Anne’s memory; the ministry came about as a direct call from God to Roy. The book not only tells of the role of Roy and Anne Porter in this ministry, but it tells of how their family also became involved. The Egg is written as an encouragement to other Christians in ministry, and most importantly to the Glory of God.
