Responsorial Psalm (Psalm 18)

R.    In my distress I called upon the Lord, and he heard my voice.
In my distress I called upon the LORD
    and cried out to my God;
From his temple he heard my voice,
    and my cry to him reached his ears. 
R.    In my distress I called upon the Lord, and he heard my voice.

I guess we all know to call on the Lord when we are in trouble, and it’s not a bad prayer. And as the Psalmist reminds us, even then God hears our voice, our cry reaches God’s ears.
