The gospel preached by the apostles (Mark 16:15), was the glad tidings of salvation to every creature during this period, though their commission did not go so far as Paul's—the gospel of the glory. The gospel of the kingdom is the glad tidings of the coming reign of Christ on earth.
“We see not yet all things put under Him." Heb. 2:8. At present He is cut off, and has nothing as Messiah. He does not take the book of judgments and inheritance until the redeemed are with Him (Rev. 5). All who compose the full complement of the first resurrection live and reign with Christ a thousand years. May our hearts be kept patiently waiting for Him (Rev. 20:4, 5).
