John 16:21; John 16:33

21 "Whenever a woman is in labor she has pain, because her hour has come; but when she gives birth to the child, she no longer remembers the anguish because of the joy that a child has been born into the world.

33 "These things I have spoken to you, so that in Me you may have peace. In the world you have tribulation, but take courage; I have overcome the world."
