The text of some anthems comes from the psalms. Reading the psalms, for me, automatically invokes the memory of those anthems. I can hear, sing, feel the anthem. In that recollection, I am re-living the moment in the worship space. Re-living that moment, I worship again.Music in worship engages the right brain, the non-analytic portion. It allows us to worship from a deeper, more primitive part of our being. It provides a different understanding and appreciation of our Creator.
