How do we know God's promises to David are true?

The truth of God's promises to David is underscored by the prophetic words delivered to him by Nathan, affirming the establishment of David's kingdom and lineage. These promises not only highlight David's immediate successes but also point forward to the coming Messiah, Jesus Christ, who is referred to as the Son of David. This connection reinforces the permanence of God's covenant, as seen in the unfolding narrative of Scripture where Christ fulfills these ancient prophecies, expanding the promise to cover His spiritual kingdom and church.
