The term Easter comes from Eostre, the Saxon goddess celebrated at the spring equinox. The equinoctial feast actually goes back to prehistoric times, suggesting man has celebrated balance ever since his conscious awareness allowed him to recognize the equal length of day and night.
And what fortune that Christianity chose the term to celebrate its highest holy day! Celebrating the balance of humanity and divinity in Jesus. And the potential of celebrating the same in ourselves—in this life.
Imagine! A balance in our personalities–of introvert and extrovert traits, of thinking and feeling functions, and of all the other opposites that pull us in two directions.
God designed this balance for all of us—a balance of work and play, of compassion and introspection, of words and silence, of activity and rest.
And beneath that balance a sense that God was/is/will be intertwining all the traits of our personality in exactly the tapestry design that He always intended.
