It is not the opposition of the world that endangers us the most; it is the evil cherished in the hearts of professed believers that works our most grievous disaster and most retards the progress of God's cause. There is no surer way of weakening our spirituality than by being envious, suspicious of one another, full of faultfinding and evil surmising. “This wisdom descendeth not from above, but is earthly, sensual, devilish. For where envying and strife is, there is confusion and every evil work. But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be entreated, full of mercy and good fruits, without partiality, and without hypocrisy. And the fruit of righteousness is sown in peace of them that make peace.” James 3:15-18. CCh 44.4
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. Then we shall work together without a thought of collision. CCh 44.5
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. Then we shall be as trees of righteousness, planted by the Lord, and watered by the river of life. And how fruitful we shall be! Did not Christ say: “Herein is My Father glorified, that ye bear much fruit”? John 15:8. CCh 45.1
When Christ's prayer is fully believed, when its instruction is brought into the daily life of God's people, 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. When we strive for this unity as God desires us to strive for it, it will come to us.6Testimonies for the Church 8:242, 243 CCh 45.2
It is not a great number of institutions, large buildings, and outward display that God requires, but the harmonious action of a peculiar people, a people chosen by God and precious, united with one another, their life hid with Christ in God. Every man is to stand in his lot and place, exerting a right influence in thought, word, and deed. When all God's workers do this, and not till then, His work will be a complete, symmetrical whole.7Testimonies for the Church 8:183 CCh 45.3
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.8Testimonies for the Church 8:239 CCh 45.4
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. But God cannot make them one in Christ unless they are willing to give up their own way for His way.9Testimonies for the Church 8:243 CCh 45.5
