David highlights God's unique favor towards the children of Abraham, choosing them as His special people over all others and establishing His sanctuary as a place to dwell among them. He emphasizes that while the sanctuary was accessible to all Jews, God's presence was only with those who sincerely feared and served Him, having purified themselves from worldly influences to commit to holiness and righteousness. Furthermore, with the temple's construction showcasing God's grace more prominently, David celebrates this grace in beautiful poetry, inspiring true believers to continue their service and honor Him diligently.
