How long will David's house, kingdom, and throne be established?
The promise declares David's house, kingdom, and throne will be established forever—not merely for a thousand years, but eternally. His royal line continues through Solomon to the Messiah Christ Himself, and the throne endures into the eternal state. This is an everlasting establishment.
Les explains that God may chasten and punish, but His mercy will not depart as it did from Saul. The promise to David's house—the royal family beginning with David, carried through Solomon all the way to Messiah Christ—is that house, kingdom, and throne are established forever, not merely a thousand years. Les feels this means the whole millennial economy goes right on into the eternal state. Revelation 22 describes the same setup: Israel as head of the nations, Christ as King of kings and Lord of lords, no more curse, the throne of God and the Lamb in the center, and believers from the ages serving and seeing His face. God is eternal and Spirit.
