Psalms 31: Oh boy, here we go again. Just another psalm about God, in which the writer begs for his protection and mercy. Yup, it's all about praising God for being awesome and just and good. As per usual, you can expect the writer to request mercy, strength and protection. And, of course, the writer will also talk about how wicked and sinful people are. Let's face it, it's like every other psalm out there.
