The egg itself became a symbol of the Resurrection. Just as Jesus rose from the tomb, the egg symbolized new life emerging from the eggshell. In the Orthodox tradition, eggs are painted red to symbolize the blood that Jesus shed on the cross. The egg-coloring tradition has continued even in modern secular nations.Eggs are believed to be a symbol of fertility and the rebirth of nature after the dead of winter

Why do we hide eggs at Easter? In many pre-Christian societies eggs held associations with spring and new life. Early Christians adapted these beliefs, making the egg a symbol of the resurrection and the empty shell a metaphor for Jesus' tomb.
