Singing is such a powerful way to compress emotion into a slice of time. We sing at birthdays, weddings, and funerals - and at church services in between. We sing when gathered in large crowds - such as sporting events.
And - who doesn't love that scene at the end of the last Lord of the Rings movie - the Return of the King - when Aragorn is finally crowned King - and he makes a tiny speech - and then he sings - and it's so cool!
Imagine. What would that even sound like for God to sing over you? Would He have a different song for each of us - or would He welcome all with the same song? We'll have to ask some day. All I know for sure is that - no one exults over someone with joy who isn't pretty important to them.
And you thought you felt put on the spot when someone tried to sing to you at your last birthday.
Better get used to it though - I doubt God's going to ratchet back His feelings towards you any time soon.
