I imagine it does God's heart good to hear little kids singing about Him. God's not vain, obviously, but I think He would like it because those childhood songs have a way of sticking with a person, and their messages might help us live our lives better, and get back to Him when our number's up. I am glad Riley already has some in her repertoire.
And this scripture:
For my soul delighteth in the song of the hearth; yea, the song of the righteous is a prayer unto me, and it shall be answered with a blessing upon their heads. - D&C 25:12Amen and AMEN.
(I just decided to make this into my theme this week. The week of uplifting music. I think it might be a moment of genius on my part. And to implement it...if you feel so inclined, send any and all worthy music my way - I would really love some assistance!)
