It’s very important to remember that Easter is not some memorial to a really nice religious teacher, who lived 2,000 years ago and had some really good teachings that people wrote in a book.
There are lots of teachers out there.
You see Easter a celebration of the fact that he is alive today. No one else can say that.
“... by being raised from the dead he was proved to be the mighty Son of God, with the holy nature of God himself.”(Romans 1:4, LB)
