 This is a form of perseverance in love, in union with God. Persevering even in tears. Weeping is a good thing. St Josemaria comments on this and says, Being a common little fellow, I cry my eyes out and wail to heaven and earth to make out for those times when I lost him through my own fault and didn't cry. And then we see you Jesus, you God, playing with her. How beautiful it is. God plays with us.
