Shout for joy to the Lord, all the earth. Psalm 100:1
I am not noted for a good singing voice. Therefore I tend to sing very quietly or not at all. I now realise I should sing with all my heart, even if it is quietly. It is not the quality that is important, but the praise from my heart. Whenever I despair about my singing, I remember that when singing in heaven in, it will be perfect.
