The Things Which "SHALL BE HEREAFTER."

Literally "after these".

The "THINGS" which shall come to pass after the "Church Period" ends.

The Things Which "ARE"

....The Messages to the Seven Churches,
....Relelation 2:1-3; 22.

.................These Messages were to seven churches that were in existence in John's day and to whom he personally wrote, these churches were representive churches and were typical of seven well defined periods in Church History.
Revelation is the only book in the Bible where the Divisions are given and they are given by Christ Himself.
...............The Things Which Thou Hast "SEEN".
The Vision of the Son of Man in the midst of the "Seven Lamp-stands." Revelation 1:10-20.

The "KEY" to the Book of Revelation is its three-fold division of Revelation 1:19.

..............The things which thou hast seen.
..............The things which are.
..............The things which shall be hereafter.

John's vision of the Son of Man was as He will appear at the second stage of His return, the "'Revelation."

........John's 'Sevenfold' description of the person of the 'Glorified Son of Man' is indirect evidence that John saw his vision of the Son of Man, not on a Sabbath Day [as we now call it the Lord's Day], but was moved forward by the Holy Spirit into the ''Day of the Lord" and saw Him as He will appear then as the Judge, and the coming 'sun of righteousness.'
"His Countenance was as the sun shineth in His strength."

..............This reminds us of His appearance on the Mount of Transfiguration when "His face did shine as the Sun,"
Matthew 17"2

........The prophet Malachi tells in Malachi 4:2 that when Jesus comes back He will be the sun of righteousness.
And the sword, like the 'Sword of the Spirit' will be two-edged also, for the protection of His people and the destruction of His enemies.

This is still further proof that John's vision of Christ was as He shall appear in the "Day of the Lord".
"Out of His mouth went a sharp two-edged sword."

..........................This is not the 'sword of the spirit' which is the Word of God in Ephesians 6:17.

......This is the 'sword of justice' for the Son of Man, out of whose mouth this sword comes, is the "White Horse Rider" of Revelation 19:11-15," out of whose mouth goeth a sharp sword, that with it He should smite the nations."

The ministers of Christ get their power and office from Him and He holds them in His hand.

...........................If they are false, no one can deliver them from His power and if they are true and loyal, no one can touch or harm them.
"In His right hand seven stars"

The Seven Stars stand for the 'angels' of the 'Seven Churches'.

The angels are not angelic beings but the Messengers or Ministers of the churches.
"His voice as the sound of many waters."

.....................There is nothing more beautiful than the sound of a babbling brook or more roaring than the rush of water over a falls and nothing more fearful than words from a judge to a criminal; but how terrifying the voice of the Son of Man will be on Judgement Day.; "Depart from me, ye cursed, into everlasting fire, prepared for the Devil and his angels." Matthew 25:41

"His feet like unto fine brass, as if they burned in a furnace."

...............In that day those feet that walked the road of suffering will be like unto brass, that shall tread and crush Antichrist and Satan when He comes.

"His eyes were a flame of fire."

.....................While He was here on earth, his eyes read the thoughts of men, so when He sits as the Judge of men, all things will be naked and open before Him.
The "White Hair" of the Son of Man
.........refers to His age and His dignity,
not that His hair was made white by age,
.........because the Eternal never grows old,
but it speaks of wisdom and experience
and His character's honor.
As the title "Ancient of Days" is applied to the
....."Son of Man" [Christ Jesus] at the time He
..............takes on Judgeship Daniel 7:9-10,
which is not until after the Rapture of the Church,
we have proof that John's vision belongs to the
......................"Day of the Lord."
