How does a bunny or eggs relate to Easter?
As with many symbols and traditions of Christianity, the Easter Bunny evolved from associations with nonreligious origins. Rabbits are widely recognized as representing fertility and abundant new life since they give birth to many babies every spring. The parallel with the new life given by God through the resurrection of Jesus on Easter explains the use of a rabbit as a representative of Easter.
Eggs are also symbols of fertility and new life. Beyond those associations, eggs are one of the foods frequently forbidden during Lent. For those who follow this practice, Easter may be celebrated with foods made with eggs. Decorations on the eggs may carry religious significance or may represent the colors of spring flowers coming to life.
