A common misinterpretation views David's rhetorical questions as self-doubt or lack of faith in God's promises, rather than an expression of awe-filled gratitude; others might see it as excessive self-deprecation promoting low self-esteem, ignoring the context of worshipful recognition of God's unmerited elevation of David from shepherd to king, or apply it legalistically as a required formula for prayer without grasping its heart of reverent wonder.
II Samuel 7:18
King James Version (1769)
18 Then went king David in, and sat before the Lord, and he said, Who am I, O Lord God? and what is my house, that thou hast brought me hitherto?
In this moment of profound humility, David enters the Lord's presence and marvels at God's extraordinary grace, questioning his own insignificance and that of his family compared to the divine favor of being brought to such a position of blessing and covenant promise, highlighting themes of God's sovereign election and unmerited kindness toward His servant.
