It will be like a woman suffering the pains of labor. When her child is born, her anguish gives way to joy because she has brought a new baby into the world. 22 So you have sorrow now, but I will see you again; then you will rejoice, and no one can rob you of that joy.
Clearly this is an indication of new life, Jesus gives us the image of childbirth as an illustration of his resurrection.
A new world, a new creation as on the last day of the week he says "it is finished " and on the sabbath he rests and on the first day of the week his newly created kingdom is birthed.
