Rev 1:7-11

THE LORD’S DAY
“In that Day, it shall be the LORD one and His name one.”  Zech 14:9

From Rev 1:7 to Rev 4:1, the Spirit of Christ leads us into the LORD’s Day. In Rev 4 and 5, the Spirit of Christ as the Angel takes us to the New Heavens and New Earth. Throughout Revelation, John departs from his chronological path several times, to return to these two time periods. The Book of Revelation begins and ends with the LORD’s Day and the New Heavens and the New Earth.

Many wonder why John used the expression “the LORD’s Day” and not “the Day of the Lord?”

The expression “Day of the Lord” in the New Testament always refers to the Day of Christ, because Christ is the Lord in the New Testament. But on “the LORD’s Day” God will become our Lord again. In the Book of Revelation, the Apostle John never called Christ the Lord, in the LORD’s Day, or thereafter. He used the expression “LORD’s Day,” rather than “Day of the Lord,” to make it clear that the LORD in this Day is the Father. The LORD’s Day is the Day when Christ submits to God (1 Cor 15:28) and Christ and God become as “one unit” again, as they were in the Old Testament.
7 Behold, he is coming with the clouds, and every eye will see him, including those who pierced him. All the tribes of the earth will mourn over him. Even so, Amen. 
Rev 1:7
Behold He is coming in the clouds – this is the description of the LORD’s Day that Christ gave us in Matt 24:30, from Dan 7:13. The Book of Daniel is the foundation of the Book of Revelation. Daniel saw the Spirit of Christ as “the Son of Man,” coming toward the “Ancient of Days.”

Every eye will see Him, even those who pierced Him – In Matt 24:30, Jesus also quoted this famous verse of Zech 12:10.
8 “I am the Alpha and the Omega, the Beginning and the End,” says the Lord God, “who is and who was and who is to come, the Almighty.” 
Rev 1:8
I am the Alpha and the Omega – have we really heard God’s voice here (John 5:37)? The Spirit of Christ, as the Word, is speaking for the invisible God, as He did in the Old Testament. Zechariah prophesied, “In that Day, it shall be the LORD one (ECHAD) and His name one.” Christ and God again form “one unit” as they did in the Old Testament, ie Yihvah our ELOHIM (I), Yihvah (and the Father), ECHAD (are one).

The meaning of “Alpha and the Omega” and “the First and the Last” is that God was “the LORD” before Christ became “the Lord,” and God is now “the LORD” again. Paul said “when all things are submitted to Christ then Christ will submit to God.” (1 Cor 15:28)

Says the Lord God – this is the first time that God has been called the Lord, since Christ’s resurrection, except when calling God “the Lord of creation.” In the Book of Revelation, God is the only Lord after the Lord’s Day.

the Almighty – in Exod 6:3, Yihvah ELOHIM (Christ as the ELOHIM) told the people of Israel, “I appeared to Abraham, and Isaac, and Jacob as “God Almighty” but by my name Yihvah (He WILL BE) I was not known to them.” “El Shaddai” meaning “God Almighty” appeared 6 times in the Old Testament, and will appear 6 times in the Book of Revelation.
9 I John, your brother and partaker with you in oppression and kingdom and perseverance which are in Jesus, was on the isle that is called Patmos because of God’s Word and the testimony of Jesus Christ. 
Rev 1:9
On the island called Patmos – a Greek island of 35 square km, where persons were exiled. John as promised by Jesus, in John 21:23, was not martyred, but here wrote the Book of Revelation.
10 I was in spirit in the Lord’s day, and I heard behind me a loud voice, as of a trumpet 
Rev 1:10
in spirit – the phrase “spirit” without the Greek article after the Day of Pentecost describes the anointing of the spirit of God. The expression “in spirit” is also used in Rev 4:2, “I became as in spirit, and behold a throne was standing in heaven.”  This is similar to Ezek 3:12,14; 8:3; 11:1,24; 43:5 which describes the anointing of the Spirit of Christ that lifted up Ezekiel. The Spirit of Christ was the Holy Spirit of the Old Testament.

in the LORD’s Day – in the Greek language, one is “in” a time, and not “on” a time, as in English. So John became as “in spirit in the LORD’s Day.” In Rev 4:2, he became as “in spirit” before a throne, meaning that he was “transported” by the spirit of God, into that time.

a loud voice as a trumpet – the symbolism of the trumpet, tells of the LORD’s Day, see Mat 24:31. In the New Testament, the trumpet is almost exclusively used to signify the last days, and the last trumpet, signifies the LORD’s Day. Paul told us that the Lord “will descend with the voice of the Archangel and the trumpet of God” (1Thes 4:16).  Jesus said that the dead will “hear his voice.” (John 5:28)
11 saying, “What you see, write in a book and send to the seven assemblies: to Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia, and to Laodicea.” 
Rev 1:11
Write in book what you see – more literally, a papyrus roll.

Send it to the seven churches – it must have been thrilling for these churches to have received this papyrus roll, unveiling a great mystery, sent by the Apostle John.
