In response to God’s promise to establish his seed forever, David responded in humility, asking who am I to be blessed so tremendously by the Lord. David displays not only here, but in all his life, a humble attitude which caused the Lord to exalt him to serve him as king. If we desire to be used by the Lord, we must display that same humility and meekness. Those who abase themselves before the Lord shall be exalted, but those who exalt themselves in pride shall be abased.
