If there is only one gospel …
Why if? Paul himself tells us that there is only one gospel.
…. what do you do with this verse
[Rev 14:6 KJV] 6 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,
[Rev 14:7 KJV] 7 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.
What do I do with it? I believe it.
It does not say believe Christ died for our sins was buried rose again nor the kingdom is at hand
All of those things go hand in hand with fearing the one God.
