One With Christ in God^{*1904, Testimonies for the Church 8:239-243.}

The Lord calls for men of genuine faith and sound minds, men who recognize the distinction between the true and the false. Each one should be on his guard, studying and practicing the lessons given in the seventeenth chapter of John, and preserving a living faith in the truth for this time. We need that self-control which will enable us to bring our habits into harmony with the prayer of Christ.3TT 243.1

The instruction given me by One of authority is that we are to learn to answer the prayer recorded in the seventeenth chapter of John. We are to make this prayer our first study. Every gospel minister, every medical missionary, is to learn the science of this prayer. My brethren and sisters, I ask you to heed these words and to bring to your study a calm, humble, contrite spirit, and the healthy energies of a mind under the control of God. Those who fail to learn the lessons contained in this prayer are in danger of making one-sided developments, which no future training will ever fully correct.3TT 243.2

“Neither pray I for these alone,” Christ said, “but for them also which shall believe on Me through their word; that they all may be one; as Thou, Father, art in Me, and I in Thee, that they also may be one in Us: that the world may believe that Thou hast sent Me.3TT 243.3

“And the glory which Thou gavest Me I have given them; that they may be one, even as We are one: I in them, and Thou in Me, that they may be made perfect in one; and that the world may know that Thou hast sent Me, and hast loved them, as Thou hast loved Me.3TT 243.4

“Father, I will that they also, whom Thou hast given Me, be with Me where I am; that they may behold My glory, which Thou hast given Me: for Thou lovedst Me before the foundation of the world. O righteous Father, the world hath not known Thee: but I have known Thee, and these have known that Thou hast sent Me. And I have declared unto them Thy name, and will declare it: that the love wherewith Thou hast loved Me may be in them, and I in them.” John 17:20-26.3TT 243.5

It is the purpose of God that His children shall blend in unity. Do they not expect to live together in the same heaven? Is Christ divided against Himself? Will He give His people success before they sweep away the rubbish of evil surmising and discord, before the laborers, with unity of purpose, devote heart and mind and strength to the work so holy in God's sight? Union brings strength; disunion, weakness. United with one another, working together in harmony for the salvation of men, we shall indeed be “laborers together with God.” Those who refuse to work in harmony greatly dishonor God. The enemy of souls delights to see them working at cross purposes with one another. Such ones need to cultivate brotherly love and tenderness of heart. If they could draw aside the curtain veiling the future and see the result of their disunion they would surely be led to repent.3TT 244.1
