One of my favourite writers is Henri Nouwen. In his book, "Turning my mourning into Dancing", he says:
"If God is found in our hard times, then all of life, no matter how
apparently insignificant or difficult, can open us to God's work among
us. To be grateful does not mean repressing our remembered hurts. But
when we come to God with our hurts - honestly, not superficially -
something life changing can begin slowly to happen. We discover how God
is the One who invites us to healing. We realise that any dance of
celebration must weave both the sorrows and the blessings into a joyful
Gratitude in its deepest sense means to live life as a gift to be
received thankfully. And true gratitude embraces all of life: the good
and the bad, the joyful and the painful, the holy and the not-so-holy.
We do this because we become aware of God's life, God's presence in the
middle of ALL that happens..."
