When translating a Bible verse it is best to break it into parts. The verse Matthew 16:28 is printed below. It will be dissected to determine its underlying meaning and determine the Matthew 16:28 explanation.
The last trumpet has sounded. The wars have ended. It is a new day and a new heaven and a new earth is entering from the heavens. The first heaven and the first earth are no more. As John views this phenomenon of Revelation 21, his description is that of beauty and you can hear the peace as he speaks. John calls the new city the holy city, New Jerusalem adorned as a bride. He hears the great voice of God as it is announced that the tabernacle of God is now with men and that He will dwell with them and they shall be His people and He will be their God. It is the time that all Christians live for. No matter what the differences may have been, they are forgotten now.
