14:6 everlasting gospel. This is the final, climactic, reference to the gospel in the Bible. It is called “everlasting,” so it can be no different from the gospel preached by Paul. In fact, it will be proclaimed by an angel from heaven, and Paul had specifically warned against any gospel preached by an angel if it was different from the gospel he preached (Galatians 1:8).
14:7 loud voice. Evidently the angel will be flying from nation to nation, shouting it loudly enough so that everyone on earth can hear, so that all will hear the gospel one last time before it is too late.
14:7 worship him that made heaven. The angel thus recognizes, and so should we, that supernatural creation of all things by Jesus Christ (John 1:1-3) is the very foundation of His gospel. The gospel also includes His redeeming death and resurrection (I Corinthians 15:1-4), plus His coming kingdom (Matthew 4:23), but these are meaningless and impossible without His prior work of creation (see also Colossians 1:16-20). Creationism is not simply a peripheral doctrine, but is foundational to everything else, and it will be absolutely essential in this coming time when evolutionary pantheistic humanism dominates the world.
