Isaiah 12:1-3 NIV
In that day you will say:
I will praise you, Lord.
    Although you were angry with me,
your anger has turned away
    and you have comforted me.
Surely God is my salvation;
    I will trust and not be afraid.
The Lord, the Lord himself, 
   is my strength and my defence;
    he has become my salvation.
With joy you will draw water
    from the wells of salvation. 

John 15:9-11 NIV
As the Father has loved me, so have I loved you.
Now remain in my love. If you keep my commands, you will remain in my love,
   just as I have kept my Father’s commands and remain in his love. 
I have told you this so that my joy may be in you and that your joy may be complete.

John 16:19A-24 NIV
In a little while you will see me no more, and then after a little while you will see me? 
Very truly I tell you, you will weep and mourn while the world rejoices.
You will grieve, but your grief will turn to joy. 
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. 
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. 
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. 
Until now you have not asked for anything in my name.
Ask and you will receive, and your joy will be complete.

And so … let us pray for and work to grow the fruit of joy in our life
