The Resurrection and the Life

Jesus said to her,
“Your brother will rise.” 

Martha said to him,
“I know he will rise,
in the resurrection on the last day.” 

Jesus told her,
“I am the resurrection and the life; whoever believes in me, even if he dies, will live, and everyone who lives and believes in me will never die." 

(John 11: 23-25)

I am the resurrection and the life. A final hope, a theological concept, is revealed in person. Eschaton made flesh.

That's the sacramental mystery at the heart of Christianity.
