"Here I am, down on my knees again surrendering all, surrendering all.
Find me here Lord, as you draw me near. Desperate for you, desperate you I surrender..."
Because when you're on the edge of the highest cliff, if you're on stood up there and I push you, I'm sure you'll fall down. But if you kneel down I'm going to need more than one push if I want to put you out there. By the other hand, when I'm down on my knees I do in front of you and I admit that you are more than me and I surrender all by myself to you.
