The Psalter (Book of Praises) is not just a box that someone randomly tossed their entire record collection into and we get to pull out at will. It is an organized book that helps us understand who we are as people by helping us to see who God is.
The Psalms guides our hearts, minds, affections, emotions, and loves. This is God’s inspired songbook and we should allow God the Holy Spirit to change us through these songs.
