What does it mean that God promised David an eternal kingdom?

In 2 Samuel 7:16, God implied that David's lineage would lead to an everlasting kingdom, a promise that ultimately points to Jesus Christ. Though Solomon would build the physical temple, it is Jesus, referred to as the 'Son of David,' who establishes the true spiritual kingdom. This promise illustrates God's faithfulness to His covenant and highlights Jesus' rightful place as king over all creation. Christians recognize that through faith in Christ, they are part of this eternal kingdom, which will never end, fulfilling God's promise made to David and shown throughout the New Testament.
