Psalm 28. This week's Sabbath in the Psalms sees the Psalmist begin with urgent requests, but in the middle of the chapter, the tone changes, as if his prayers have been answered mid-sentence, and we are reminded again of the Lord's promises. As we ask him to hear us, he does, and as we ask him to guide us, he does. His mercies are new every morning, great is his faithfulness (Lamentations 3).
