As times change, people change—the way we think and process information changes. We now live in a rational age. Things need to make sense. That was not so much the case in the past when people took so much on faith.
I heard some say that Christianity is dead. That would be a shame. Religion upholds moral fiber and integrity that permeates all aspects of a culture. It is only the understanding of any religion, all religions, that must evolve over time to interface with the mentality of the times. That is not the death, but rather the rebirth, of the religion. To my experience, even Christian leaders who I have spoken with thirst for that deeper understanding. Like all religions, throughout time the understanding must be reborn.
Perhaps that is a deeper meaning of Easter: the resurrection of Christ, of Christianity, to be renewed every year.
