I believe Ellen White was the last person Jesus gifted with the spirit of prophecy.

The final message will be
The Righteousness of Christ which is the very essence of the three angels' message.

Present truth is THAT MESSAGE
It is that message which needs to be understood.

When it is fully understood there will be a revival.
It is only when that message becomes not only a message but the motive and meaning of our lives, that the latter rain will come.

Amen! In particular, too, the righteousness of Christ as reflected in the lives of Remnant Church believers. The righteousness of Jesus shinning through believers speaks more eloquently to the issues of the Great Controversy than when Jesus reflected the glory of God while here in the likeness of sinful flesh. It is this testimony - Christ in you, the hope of glory - that will force evil angels and unbelievers to confess Jesus is right, they are wrong and they deserve to die forever.

Funny you should bring that up, as I was going to start a thread on that as we came across that on our Wednesday night meeting, and there was some 'lively' discussion as to what constitutes the 3rd Angels message...

The Heart of God’s Last Message
"Several have written to me, inquiring if the message of justification by faith is the third angel’s message, and I have answered, “It is the third angel’s message in verity.”—Selected Messages 1:372 (1890). LDE 199.4

The Lord in His great mercy sent a most precious message to His people through Elders [E.J.] Waggoner and [A. T.] Jones. This message was to bring more prominently before the world the uplifted Saviour, the sacrifice for the sins of the whole world. It presented justification through faith in the Surety; it invited the people to receive the righteousness of Christ, which is made manifest in obedience to all the commandments of God. LDE 200.1

Many had lost sight of Jesus. They needed to have their eyes directed to His divine person, His merits, and His changeless love for the human family. All power is given into His hands, that He may dispense rich gifts unto men, imparting the priceless gift of His own righteousness to the helpless human agent. This is the message that God commanded to be given to the world. It is the third angel’s message, which is to be proclaimed with a loud voice, and attended with the outpouring of His Spirit in a large measure.—Testimonies to Ministers and Gospel Workers, 91, 92 (1895). LDE 200.2

The message of Christ’s righteousness is to sound from one end of the earth to the other to prepare the way of the Lord. This is the glory of God, which closes the work of the third angel.—Testimonies for the Church 6:19 (1900). LDE 200.3

Though the Loud Cry was to have begun by 1892, it was muffled when the church rejected the message of Righteousness by Faith in 1888. Thus, the scroll which contained the “additional” message that was to give “power and force” to the Third Angel’s Message, for the time then being ceased unrolling.

And consequently, instead of becoming the light of the world, the church herself went into darkness. Seeing this, the Spirit of Truth made a fearful pronouncement of doom upon unrepentant Laodiceans, while giving joyous promise of future glory to all who will arise and walk in the light that proceeds from the throne.

“How will any of our brethren know when this light shall come to the people of God?” was the sweeping question then asked by Inspiration. And the inspired answer was: “As yet we have certainly not seen the light that answers to this description. God has light for His people, and all who accept it will see the sinfulness of remaining in a lukewarm condition.”-The Review and Herald, Oct. 7, 1890.

“In the manifestation of the power that lightens the earth with its glory, they will see only something which in their blindness they think dangerous, something which will arouse their fears and they will brace themselves to resist it. Because the Lord does not work according to their expectations and ideal, they will oppose the work. Why, they say, should we not know the Spirit of God, when we have been in the work so many years?”-Bible Training School, 1907. (Reprinted in The Review and Herald, Nov. 7 1918.)

The message swells to a Loud Cry by virtue of an “addition” which gives it “power and force.”- Early Writings, p. 277.
