BIBLE READING: Acts 2, 8/ Hebrews 12.28/ Revelation 1.6
The Kingdom existed, and continues to exist, in power. The Holy Spirit came on the first Day of Pentecost at Jerusalem. People who believed, repented, and were baptized were added to the kingdom/church. From that point, the kingdom/church was spoken of as being in existence. Christ is now reigning in heaven over His kingdom, and he will continue to reign until He returns at the end of time to take His faithful followers with Him to heaven.
