In his gospel John strategically places seven miracles of Jesus as signs to guide us. These signs are intended to point us to the right way to believe in Jesus the Christ.
But then as we come to the final few chapters of the book of John we discover an eighth, hidden sign. It is the sign of new beginnings.
New beginning is one of John's major themes in his gospel. And when we read the account of Mary Magdalene coming to the tomb early on the third day after Christ's crucifixion, only to find the tomb empty, we are seeing the new beginning of the world. Jesus Christ is the firstborn of the new humanity. In Jesus Christ humanity finds its NEW GENESIS.
In Jesus Christ we recover our original vocation: to make the world a garden.
