Neither pray I for these alone, 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. John 17:20, 21. AG 210.1
After the descent of the Holy Spirit the disciples went forth to proclaim a risen Saviour, their one desire the salvation of souls. They rejoiced in the sweetness of the communion with saints. They were tender, thoughtful, self-denying, willing to make any sacrifice for the truth's sake. In their daily association with one another they revealed the love that Christ had commanded them to reveal.... AG 210.2
Harmony and union existing among men of varied dispositions is the strongest witness that can be borne that God has sent His Son into the world to save sinners. It is our privilege to bear this witness. But, in order to do this, we must place ourselves under Christ's command. Our characters must be molded in harmony with His character, our wills must be surrendered to His will.58Testimonies for the Church 8:241-243. AG 210.3
We are of the same faith, members of one family, all children of the same heavenly Father, with the same blessed hope of immortality. How close and tender should be the tie that binds us together. The people of the world are watching us to see if our faith is exerting a sanctifying influence upon our hearts. They are quick to discern every defect in our lives, every inconsistency in our actions. Let us give them no occasion to reproach our faith.... AG 210.4
Little differences dwelt upon lead to actions that destroy Christian fellowship. Let us not allow the enemy thus to gain the advantage over us. Let us keep drawing nearer to God and to one another.... The heart of the Saviour is set upon His followers’ fulfilling God's purpose in all its height and depth. They are to be one in Him, even though they are scattered the world over.... When Christ's prayer is fully believed, ... unity of action will be seen in our ranks. Brother will be bound to brother by the golden bonds of the love of Christ. The Spirit of God alone can bring about this oneness. He who sanctified Himself can sanctify His disciples. United with Him, they will be united with one another in the most holy faith.59Testimonies for the Church 8:242, 243. AG 210.5
