I do this often - pray to wake up "happy" before my alarm goes off. I do this because when I start my day well, the rest of it usually follows suit. It's only recently that I've attributed this "waking up" to Jesus and not my body's own clock. And so now, I just ask that He wake me up, knowing He will, and yet still sometimes surprised when He does. Little faith, what will it take for you to grow?
"The steadfast love of the Lord never ceases;
his mercies never come to an end;
they are new every morning;
great is your faithfulness."
