This is not a day for mourning.  This is a day to give thanks for love.
Love is the joy of our lives; the loss of it is our most personal pain. 
The love of a mother or a father for their children is wonderful, whether it’s expressed in tenderness or correction toward the child; whether it comes as the speech of pride before an acquaintance or a withering venom to one who threatens the child’s happiness. 
Love of another—both coming and going—is a cause of joy and a motive of thanksgiving.
But love lost: this is a source of deep grief to us. 
It brings out the worst in us: maybe depression; maybe anger, venom.
Those who mistreated Jesus and killed him: they were without love.
Their anger, their poison was not truly against Jesus, but against an enemy they could not recognize: the one who stole love from their lives, the Evil one, the jealous spirit whose joy is our suffering. 
Jesus takes it: takes the venom and hatred, the abuse and bitterness, as one who understands us, knows our longing for love and our destiny in love.  And as one who is willing, in love for us, to do what’s necessary to guide our hearts to reconciliation and peace, by his silent, noble suffering.
In this noble suffering is our hope.
Jesus helps us overcome the disappointment of our lost loves.
Jesus shows us the way to peace.
Jesus makes a bridge between God and humankind (between you and me, too!) so that we may be witnesses of love in the world.
This is a day to give thanks for such a Love.
