According to David, mankind is not designed to live in heaven. Psalm 115:16, “The highest heavens belong to the LORD, but the earth He has given to mankind.” Isaiah 45:12 “It is I who made the earth and created man upon it.” This verse also indicates that mankind was designed to remain on the earth. This is also indicative for the creation of a new heaven and new earth, uncorrupted and perfect where the New Jerusalem will be placed onto the earth by the Creator Himself.
