19Jesus saw that they wanted to ask him about this, so he said to them, “Are you asking one another what I meant when I said, ‘In a little while you will see me no more, and then after a little while you will see me’? 20I tell you the truth, you will weep and mourn while the world rejoices. You will grieve, but your grief will turn to joy. 21A woman giving birth to a child has pain because her time has come; but when her baby is born she forgets the anguish because of her joy that a child is born into the world. 22So with you: Now is your time of grief, but I will see you again and you will rejoice, and no one will take away your joy. 23In that day you will no longer ask me anything. I tell you the truth, my Father will give you whatever you ask in my name. 24Until now you have not asked for anything in my name. Ask and you will receive, and your joy will be complete.
Proves my point. Jesus didn’t say not to grieve because he knew it was part of the human heart and process of loss.
