John 16:20-24 NIV
20 Very truly I tell you, you will weep and mourn while the world rejoices. You will grieve, but your grief will turn to joy. 21 A 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. 22 So 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. 23 In that day you will no longer ask me anything. Very truly I tell you, my Father will give you whatever you ask in my name. 24 Until now you have not asked for anything in my name. Ask and you will receive, and your joy will be complete.
1 Peter 1:8-9 NIV
8 Though you have not seen him, you love him; and even though you do not see him now, you believe in him and are filled with an inexpressible and glorious joy, 9 for you are receiving the end result of your faith, the salvation of your souls. -How often do you pray for more joy!?
