Psalm 54

They have not set God before them. Selah  

Behold, God is my helper;

vv.3-4

Read chapter 54

1 Samuel 23 gives the history for when and why David wrote this psalm.  First we see him plead with God because the Ziphites showed him cruelty for no reason when he was hiding from Saul but then he stops himself and shouts for joy. Spurgeon puts it, "David came quietly among them, hoping for a little rest in his many flights, but they deserted him in his solitary abode, and betrayed him. He turns to God in prayer, and so strong was his faith that he soon sang himself into delightful serenity. " 

We see again the word 'Selah' when this transition happens.  Remember it's a pause and contrast or connect.  More pauses in our life would, as a rule, improve our devotions and how we live out the fruits of the Spirit within us; we are usually too much in a hurry, a little more holy meditation would make our words more suitable and our emotions more fervent.

How can you turn your complaint to joy?  Where do you need to put to death anxiety and let the promise of Christ's security reign in your emotions?
