I need a purified heart. I’ve been having some grumpy days. Instead of being thankful that I can play piano and hear it, and that I am staying well, and so on–I’ve been disappointed in my playing. I constantly worry that I’m not very good and should give up and take up another hobby like watching dandelions take over the lawn. Why do I get frustrated when my hands don’t go where they are supposed to? Am I the only one around here that needs a heart purification operation? This is a beautiful chorus but I was surprised how hard it was for me to learn. Was the result worth all the effort I put into it? More importantly, have I learned that a pure and joyful heart is more important than any accomplishments I strive for?
