"And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people, Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters." (Revelation 14:6-7)
When the Lord Jesus returned to heaven after His resurrection, He left the disciples with the Great Commission to "preach the gospel to every creature" (Mark 16:15). Unfortunately, over the centuries, there has developed much misunderstanding concerning the content of the gospel ("good tidings") and many have preached "another gospel" (Galatians 1:6) which can never save. This false gospel wears many faces, but inevitably, at its heart will be found the false hope of evolutionary humanism, glorifying man instead of God, worshipping and serving the creature more than the Creator (Romans 1:25).
We can be sure that the gospel preached in our text is the true gospel--in fact, it is called specifically the everlasting gospel! And its great burden is to call people everywhere back to faith in the one true Creator God, who made all things in heaven and earth. The Lord Jesus Christ must be accepted, first of all, as God and Creator, before it can be meaningful to present Him as Savior and Lord. Otherwise, we preach "another gospel" and "another Jesus"--neither of which are even real!
The true gospel must also present Christ as the sin-bearing, crucified, resurrected Savior (1 Corinthians 15:1-4), and as the coming King of kings and Lord of lords (Matthew 4:23; Revelation 19:16). But it must first present Him as omnipotent and offended Creator. Then only, like the angel, do we truly proclaim the everlasting gospel. HMM
