Rev 14:7

7 He said with a loud voice, “Fear God, and give him glory; for the hour of his judgment has come. Worship him who made the heaven, the earth, the sea, and the springs of waters!” 

Fear God and give Him glory – King Nebuchadnezzar, after recognizing the true God, gave God glory. (After he set up his image, the image of the beast). King Darius in Dan 6:25-27, told all men to “tremble and fear before the God of Daniel,” after Daniel broke the law that cannot be changed (Dan 6:15), (the mark of the beast).

the hour – in terms of human history, this is the 11th hour. The 12th hour is described in verse 15. The 9th and 10th hours were described in Rev 11:13, and Rev 17:12.

of His judgment has come – the outpouring of the holy spirit and the restoration of the true Gospel brings “the hour of judgment,” see John 16:8, and Gal 1:8-10. The Church treads out the fierceness of wrath of the Almighty God, striking down the Nations (or Gentiles) who have corrupted the truth; defeating them with the sword of the word of God (Rev 19:15-16).

who made theheaven and earth, and sea and “springs of waters” – the expression, “who made the heaven and earth…” was first used in the Ten Commandments, in Exodus 20:11, the commandment of the Sabbath Day. This is another hint of the “mark of the beast,” the breaking of the fourth commandment. To “heaven and earth, and sea” in Rev 10:6, is added the phrase: “springs of waters.” Springs of water throughout Revelation and John’s Gospel refer to the baptism of the holy spirit that accompanies obedience to the Gospel of Jesus Christ. The “Everlasting Gospel” is the Gospel that complies with all of the salvation conditions of Christ. These are the “measurements of the temple” (Rev 11:1), that allowed the “glory of the LORD” to come “into the house” (Ezek 43:4).
