I lay down and slept; I woke again, for the LORD sustained me.  I will not be afraid of many thousands of people who have set themselves against me all around. (ESV)
We continue to look at this Psalm where David finds himself on the run from his own son, Absalom, who is trying to kill him and take away his throne. What a great tragedy. Absalom has stolen away the hearts and minds of many of David's previously loyal subjects. There is no question that David is hurt by these circumstances. Yet, his response is inspiring.
David knows that he can leave this situation in God's hands. God is trustworthy. Those around him are not. He cannot even trust his own family. He cannot trust his friends. But, he can trust God to the point that he can go to sleep in peace even though the circumstances are not peaceful. He looks to the Lord to sustain him.
How do you deal with terrible tragedy? What do you do when you have been betrayed by your co-workers? Long-time friends? Even family members? Perhaps you have been betrayed by a spouse? This Psalm can be an encouragement to you. You need not worry about those who betray you. You can give the situation to God and leave it in his capable hands. He can give you rest.
1 Peter 5:7
 casting all your anxieties on him, because he cares for you. (ESV)
What is troubling you today? Cast it on the Lord. He cares for you. He will help all those who turn to him. Betrayed? God is your peace. He will sustain you.
