Thousands of years ago, King David wrote this above Scripture. The words'for ever and ever,'were directed through him by the Holy Ghost. As we worship God today, as the church of the living Christ, we become that 'for ever and ever'.
As you and I praise our Lord and Savior Jesus Christ; the Goliaths, the King Sauls, cave time and so on, will receive the same inherit blessings as David did;the man after God's own heart! Mountains will crumble, valleys will be leveled and all the powers of darkness will yield their resources to the King of Kings and Lord of Lords, Jesus! Yes, when David wrote, "my mouth shall speak the praise of the Lord;" he gave us beauty for ashes. Praise the Lord!
