I am writing today from the beautiful Tampa Bay area.

As we look at John 15 I would like to share one of my favorite passages from the Desire of Ages, in the chapter, Let not Your Heart be Troubled. 

“I am the Vine, ye are the branches,” Christ said to His disciples. Though He was about to be removed from them, their spiritual union with Him was to be unchanged. The connection of the branch with the vine, He said, represents the relation you are to sustain to Me. The scion is engrafted into the living vine, and fiber by fiber, vein by vein, it grows into the vine stock. The life of the vine becomes the life of the branch. So the soul dead in trespasses and sins receives life through connection with Christ. By faith in Him as a personal Saviour the union is formed. The sinner unites his weakness to Christ’s strength, his emptiness to Christ’s fullness, his frailty to Christ’s enduring might. Then he has the mind of Christ. The humanity of Christ has touched our humanity, and our humanity has touched divinity. Thus through the agency of the Holy Spirit man becomes a partaker of the divine nature. He is accepted in the Beloved.  {DA 675.3} 
     This union with Christ, once formed, must be maintained. Christ said, “Abide in Me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in Me.” This is no casual touch, no off-and-on connection. The branch becomes a part of the living vine. The communication of life, strength, and fruitfulness from the root to the branches is unobstructed and constant. Separated from the vine, the branch cannot live. No more, said Jesus, can you live apart from Me. The life you have received from Me can be preserved only by continual communion. Without Me you cannot overcome one sin, or resist one temptation.  {DA 676.1}
     “Abide in Me, and I in you.” Abiding in Christ means a constant receiving of His Spirit, a life of unreserved surrender to His service. The channel of communication must be open continually between man and his God. As the vine branch constantly draws the sap from the living vine, so are we to cling to Jesus, and receive from Him by faith the strength and perfection of His own character.  {DA 676.2} 
     The root sends its nourishment through the branch to the outermost twig. So Christ communicates the current of spiritual strength to every believer. So long as the soul is united to Christ, there is no danger that it will wither or decay.  {DA 676.3} 
     The life of the vine will be manifest in fragrant fruit on the branches. “He that abideth in Me,” said Jesus, “and I in him, the same bringeth forth much fruit: for without Me ye can do nothing.” When we live by faith on the Son of God, the fruits of the Spirit will be seen in our lives; not one will be missing.  {DA 676.4} 
     “My Father is the husbandman. Every branch in Me that beareth not fruit He taketh away.” While the graft is outwardly united with the vine, there may be no vital connection. Then there will be no growth or fruitfulness. So there may be an apparent connection with Christ without a real union with Him by faith. A profession of religion places men in the church, but the character and conduct show whether they are in connection with Christ. If they bear no fruit, they are false branches. Their separation from Christ involves a ruin as complete as that represented by the dead branch. “If a man abide not in Me,” said Christ, “he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.”  {DA 676.5} 
     “And every branch that beareth fruit, He purgeth [pruneth] it, that it may bring forth more fruit.” From the chosen twelve who had followed Jesus, one as a withered branch was about to be taken away; the rest were to pass under the pruning knife of bitter trial. Jesus with solemn tenderness explained the purpose of the husbandman. The pruning will cause pain, but it is the Father who applies the knife. He works with no wanton hand or indifferent heart. There are branches trailing upon the ground; these must be cut loose from the earthly supports to which their tendrils are fastening. They are to reach heavenward, and find their support in God. The excessive foliage that draws away the life current from the fruit must be pruned off. The overgrowth must be cut out, to give room for the healing beams of the Sun of Righteousness. The husbandman prunes away the harmful growth, that the fruit may be richer and more abundant.  {DA 676.6} 
     “Herein is My Father glorified,” said Jesus, “that ye bear much fruit.” God desires to manifest through you the holiness, the benevolence, the compassion, of His own character. Yet the Saviour does not bid the disciples labor to bear fruit. He tells them to abide in Him. “If ye abide in Me,” He says, “and My words abide in you, ye shall ask what ye will, and it shall be done unto you.” It is through the word that Christ abides in His followers. This is the same vital union that is represented by eating His flesh and drinking His blood. The words of Christ are spirit and life. Receiving them, you receive the life of the Vine. You live “by every word that proceedeth out of the mouth of God.” Matthew 4:4. The life of Christ in you produces the same fruits as in Him. Living in Christ, adhering to Christ, supported by Christ, drawing nourishment from Christ, you bear fruit after the similitude of Christ.  {DA 677.1} 
     In this last meeting with His disciples, the great desire which Christ expressed for them was that they might love one another as He had loved them. Again and again He spoke of this. “These things I command you,” He said repeatedly, “that ye love one another.” His very first injunction when alone with them in the upper chamber was, “A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.” To the disciples this commandment was new; for they had not loved one another as Christ had loved them. He saw that new ideas and impulses must control them; that new principles must be practiced by them; through His life and death they were to receive a new conception of love. The command to love one another had a new meaning in the light of His self-sacrifice. The whole work of grace is one continual service of love, of self-denying, self-sacrificing effort. During every hour of Christ’s sojourn upon the earth, the love of God was flowing from Him in irrepressible streams. All who are imbued with His Spirit will love as He loved. The very principle that actuated Christ will actuate them in all their dealing one with another.  {DA 677.2} 
     This love is the evidence of their discipleship. “By this shall all men know that ye are My disciples,” said Jesus, “if ye have love one to another.” When men are bound together, not by force or self-interest, but by love, they show the working of an influence that is above every human influence. Where this oneness exists, it is evidence that the image of God is being restored in humanity, that a new principle of life has been implanted. It shows that there is power in the divine nature to withstand the supernatural agencies of evil, and that the grace of God subdues the selfishness inherent in the natural heart.  {DA 678.1} 
     This love, manifested in the church, will surely stir the wrath of Satan. Christ did not mark out for His disciples an easy path. “If the world hate you,” He said, “ye know that it hated Me before it hated you. If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you. Remember the word that I said unto you, The servant is not greater than his lord. If they have persecuted Me, they will also persecute you; if they have kept My saying, they will keep yours also. But all these things will they do unto you for My name’s sake, because they know not Him that sent Me.” The gospel is to be carried forward by aggressive warfare, in the midst of opposition, peril, loss, and suffering. But those who do this work are only following in their Master’s steps.  {DA 678.2} 
     As the world’s Redeemer, Christ was constantly confronted with apparent failure. He, the messenger of mercy to our world, seemed to do little of the work He longed to do in uplifting and saving. Satanic influences were constantly working to oppose His way. But He would not be discouraged. Through the prophecy of Isaiah He declares, “I have labored in vain, I have spent My strength for nought, and in vain: yet surely My judgment is with the Lord, and My work with My God. . . . Though Israel be not gathered, yet shall I be glorious in the eyes of the Lord, and My God shall be My strength.” It is to Christ that the promise is given, “Thus saith the Lord, the Redeemer of Israel, and His Holy One, to Him whom man despiseth, to Him whom the nation abhorreth; . . . thus saith the Lord: . . . I will preserve Thee, and give Thee for a covenant of the people, to establish the earth, to cause to inherit the desolate heritages; that Thou mayest say to the prisoners, Go forth; to them that are in darkness, Show yourselves. . . . They shall not hunger nor thirst; neither shall the heat nor sun smite them: for He that hath mercy on them shall lead them, even by the springs of water shall He guide them.” Isaiah 49:4, 5, 7-10.  {DA 678.3} 
     Upon this word Jesus rested, and He gave Satan no advantage. When the last steps of Christ’s humiliation were to be taken, when the deepest sorrow was closing about His soul, He said to His disciples, “The prince of this world cometh, and hath nothing in Me.” “The prince of this world is judged.” Now shall he be cast out. John 14:30; 16:11; 12:31. With prophetic eye Christ traced the scenes to take place in His last great conflict. He knew that when He should exclaim, “It is finished,” all heaven would triumph. His ear caught the distant music and the shouts of victory in the heavenly courts. He knew that the knell of Satan’s empire would then be sounded, and the name of Christ would be heralded from world to world throughout the universe.  {DA 679.1}
     Christ rejoiced that He could do more for His followers than they could ask or think. He spoke with assurance, knowing that an almighty decree had been given before the world was made. He knew that truth, armed with the omnipotence of the Holy Spirit, would conquer in the contest with evil; and that the bloodstained banner would wave triumphantly over His followers. He knew that the life of His trusting disciples would be like His, a series of uninterrupted victories, not seen to be such here, but recognized as such in the great hereafter.  {DA 679.2} 
     “These things I have spoken unto you,” He said, “that in Me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.” Christ did not fail, neither was He discouraged, and His followers are to manifest a faith of the same enduring nature. They are to live as He lived, and work as He worked, because they depend on Him as the great Master Worker. Courage, energy, and perseverance they must possess. Though apparent impossibilities obstruct their way, by His grace they are to go forward. Instead of deploring difficulties, they are called upon to surmount them. They are to despair of nothing, and to hope for everything. With the golden chain of His matchless love Christ has bound them to the throne of God. It is His purpose that the highest influence in the universe, emanating from the source of all power, shall be theirs. They are to have power to resist evil, power that neither earth, nor death, nor hell can master, power that will enable them to overcome as Christ overcame.  {DA 679.3} 

Remember, in Galatians 5 all our works of the flesh are saturated in selfishness and not  one of them is good. When we are crucified with Christ all of our selfishness is crucified and then we have the fruit of the Spirit. It is called the fruit of the Spirit because it is the work of the Holy Spirit and not our own.
