It is Easter, and not Christmas, that captures the essence of what it means to be a believer.  We look at the resurrection and why this is the one Christian belief that non-believers do their very best to argue away.  But there is no scientific explanation: the truth is that we, as the faithful, simply have the gift of believing in something that only our intuition and our faith tells us is true.  And Easter ushers in a kingdom that, unlike all other kingdoms, has no end.
