The psalm appointed for this morning's principal service is Psalm 4 which begins like this:
Answer me when I call, O God, defender of my cause; *It is a good prayer for me right now because I am certainly "hard pressed" and in need of a "defender of my cause". I imagine that's true for many right now - perhaps even some who may happen to read this post.
you set me free when I am hard-pressed;
have mercy on me and hear my prayer.
