The central theme of Easter is death or, more precisely, Jesus’s triumph over death.
This is also the core of our faith. In partaking to the covenant with God, in accepting Jesus into our life, we are committed to putting our worldly self to death and embracing the birth of our spiritual self. Our worldly existence takes on a whole new meaning that we live not for the sake of satisfying our selves but to serve God and others. We no longer fear death, for we know, from the experience of Jesus, that death does not have a grip on us if we entrust our life to the power of God.
To have this sort of faith is not easy at all. Even the son of God had His moments of doubt before His demolition of death and rise to eternal glory. But Jesus on the cross has shown us, in flesh and blood, that it can be done.
