I watched him as he walked around the nursing home mumbling, not knowing fully who he was nor where he was.  We opened a hymnal and started to sing, he stopped what he was doing and came, standing nearby, to join the hymn without missing a word.  He remembered!  Israel had a hymnbook; it was called Psalms.   The tunes and chants sealed the words in their memory, so much so that the Psalms were committed to their memory and they could never forget the words and tunes of their worship.  Singing has power to help us remember. Singing is a neglected component of discipleship. Songs glue the story to our heart and mind. 

“I will sing to the Lord as long as I live; I will sing praise to my God while I have being.” Psalm 104:33 (ESV)
