What is your response when you experience suffering, especially if you know that you are suffering because of your own sin? In Psalm 38 David cries out "O Lord" many times as he expresses the depth of his pain to God, as he experiences the discipline of the Lord for sin in his own life. While we are prone to run away from discipline for our sin, this Psalm is an excellent example of the importance of crying out to God in our pain, even when it comes as a result of our own sin.
