During your life in time on earth, you get glimpses of eternity. In fact, Jesus once said that whoever believes in him has eternal life. Nevertheless, you do not experience it fully and constantly, because you are impeded by time and space. Death and resurrection deliver you from those impediments. The eternal life you have in the resurrection makes you contemporaneous with all of time and space.
History is no longer a sequence of episodes but a single image.
You see everything at once. Jesus was born in history, he lived in history, and he died in history. On Easter, however, he is set free from history, not in order to distance himself from people like you and me who still live in time and space, but in order to be totally present to us in every moment of our existence. If Easter means only that Jesus has escaped from history and has gone into semi-retirement at the right hand of God, then Easter means nothing at all to us. But that is not what Easter means.
