And we see exactly that in rev 14 during the trib.
A gathering during the trib
Days shortened.
Angels....not man preaching the gospel
Well now, we do not find what you say, in Revelation ch 14
As a matter of fact, the Scripture and Prophecy of the LORD corrects your erroneous claims.
And a third angel
followed them, calling out in a loud voice, “If anyone worships the beast and its image, and receives its mark on his forehead or on his hand, he too will drink the wine of God’s anger, poured undiluted into the cup of His wrath. And he will be tormented in fire and sulfur in the presence of the holy angels and of the Lamb. And the smoke of their torment rises forever and ever. Day and night there is no rest for those who worship the beast and its image, or for anyone who receives the mark of its name.”
Here is a call for the perseverance of the saints who keep the commandments of God and the faith of Jesus.
And I heard a voice from heaven telling me to write, “Blessed are the dead—those who die in the Lord from this moment on.”
“Yes,” says the Spirit, “they will rest from their labors, for their deeds will follow them.”
The LORD says His Saints will be preaching the Gospel in chapter 14 verse 12
The commandments of God and the faith of Jesus is found in Matthew 22:35-37
Then one of them, a lawyer, asked
Him a question, testing Him, and saying, “Teacher, which
is the great commandment in the law?”
Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’ This is
the first and great commandment. And
the second
is like it: ‘You shall love your neighbor as yourself.’ On these two commandments hang all the Law and the Prophets.”
But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria,
and to the end of the earth.” Acts ch1
And daily in the temple, and in every house, they did not cease teaching and preaching Jesus as the Christ.
Acts 5:42
