BPW 152, also the Anglcian collect for Advent 2 seems pretty darned perfect for today:

Almighty God,
give us grace to cast away the works of darkness
and to put on the armour of light,
now in the time of this mortal life,
in which your Son Jesus Christ came to us in great humility;
that on the last day,
when he shall come again in his glorious majesty
to judge the living and the dead,
we may rise to the life immortal;
through him who is alive and reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.

Even when the darkness encroaches, it is already defeated, the light is already absorbing it and replacing it with glimmers of brighteness.

In the darkness of the aftermath of the tragic accident in Glasogw yesterday

In the darkness of losing loved ones due to illness

In the darkness of our own making

Light shines

Grace is active

Hope remains,
