"Sitting on Doorknobs" The term “nest egg” usually refers to savings that grows with interest or through investments. The expression is an old one and comes from a trick that poultry farmers use to increase the likelihood that a hen’s will lay her eggs in a place they can be found. By placing a false egg, often a doorknob or a rock, in a nest, the farmer fools the chicken into laying her eggs there rather than somewhere out in the field. In our lesson today, we’ll look more closely into the practice of sitting on doorknobs. No matter how long that hen sits on a doorknob, it will never hatch! Is that not true of some of the things of this life that we put our hope in? When we have things in our lives that will never bring us lasting joy, and we continue to sit on them in hopes that they will hatch, we find ourselves caught up in the vanity of life.
