1 Chron 17:16-18

16 King David went in, took his place before GOD, and prayed:
Who am I, my Master GOD, and what is my family, that you have brought me to this place in life? 17 But that's nothing compared to what's coming, for you've also spoken of my family far into the future, given me a glimpse into tomorrow and looked on me, Master GOD, as a Somebody. 18 What's left for David to say to this — to your honoring your servant, even though you know me, just as I am?

“…you know me, just as I am”, this is why I’m not worried as I am.
