Why did David say 'Who am I?' in 1 Chronicles 17?

David’s question, 'Who am I, O Lord God, and what is my house that You have brought me hitherto?' in 1 Chronicles 17:16, illustrates profound humility and awareness of God's grace. This acknowledgment highlights David’s understanding that his status and blessings are not due to his own merits but solely the result of God’s gracious favor. In recognizing his unworthiness, David exemplifies the heart of true worship—a response to God’s kindness that leads to gratitude and praise. This attitude is foundational in understanding our own relationship with God as sinners who have received grace.
