But gradually a change came. The believers began to look for defects in others. Dwelling upon mistakes, giving place to unkind criticism, they lost sight of the Saviour and His love. They became more strict in regard to outward ceremonies, more particular about the theory than the practice of the faith. In their zeal to condemn others, they overlooked their own errors. They lost the brotherly love that Christ had enjoined, and, saddest of all, they were unconscious of their loss. They did not realize that happiness and joy were going out of their lives and that, having shut the love of God out of their hearts, they would soon walk in darkness. (AA 548.1) MC VC

John, realizing that brotherly love was waning in the church, urged upon believers the constant need of this love. His letters to the church are full of this thought. “Beloved, let us love one another,” he writes; “for love is of God; and everyone that loveth is born of God, and knoweth God. He that loveth not knoweth not God; for God is love. In this was manifested the love of God toward us, because that God sent His only-begotten Son into the world, that we might live through Him. Herein is love, not that we loved God, but that He loved us, and sent His Son to be the propitiation for our sins. Beloved, if God so loved us, we ought also to love one another.” 1 John 4:7~11. (AA 548.2) MC VC

Of the special sense in which this love should be manifested by believers, the apostle writes: “A new commandment I write unto you, which thing is true in Him and in you: because the darkness is past, and the true light now shineth. He that saith he is in the light, and hateth his brother, is in darkness even until now. He that loveth his brother abideth in the light, and there is none occasion of stumbling in him. But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.”(1 John 2:8-11) “This is the message that ye heard from the beginning, that we should love one another.”(1 John 3:11) “He that loveth not his brother abideth in death. Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him. Hereby perceive we the love of God, because He laid down His life for us: and we ought to lay down our lives for the brethren.” 1 John 3:14. (AA 548.3) MC VC

As the years went by and the number of believers grew, John labored with increasing fidelity and earnestness for his brethren. The times were full of peril for the church. Satanic delusions existed everywhere. By misrepresentation and falsehood the emissaries of Satan sought to arouse opposition against the doctrines of Christ, and in consequence dissensions and heresies were imperiling the church. Some who professed Christ claimed that His love released them from obedience to the law of God. On the other hand, many taught that it was necessary to observe the Jewish customs and ceremonies; that a mere observance of the law, without faith in the blood of Christ, was sufficient for salvation. Some held that Christ was a good man, but denied His divinity. Some who pretended to be true to the cause of God were deceivers, and in practice they denied Christ and His gospel. Living themselves in transgression, they were bringing heresies into the church. Thus many were being led into the mazes of skepticism and delusion. (AA 553.1) MC VC

John was filled with sadness as he saw these poisonous errors creeping into the church. He saw the dangers to which the church was exposed, and he met the emergency with promptness and decision. The epistles of John breathe the spirit of love. It seems as if he wrote with a pen dipped in love. But when he came in contact with those who were breaking the law of God, yet claiming that they were living without sin, he did not hesitate to warn them of their fearful deception. (AA 554.1) MC VC

Writing to a helper in the gospel work, a woman of good repute and wide influence, he said: “Many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist. Look to yourselves, that we lose not those things which we have wrought, but that we receive a full reward. Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son. If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him Godspeed: for he that biddeth him Godspeed is partaker of his evil deeds.” 2 John 1:7~11. (AA 554.2) MC VC

We are authorized to hold in the same estimation as did the beloved disciple those who claim to abide in Christ while living in transgression of God’s law. There exist in these last days evils similar to those that threatened the prosperity of the early church; and the teachings of the apostle John on these points should be carefully heeded. “You must have charity,” is the cry heard everywhere, especially from those who profess sanctification. But true charity is too pure to cover an unconfessed sin. While we are to love the souls for whom Christ died, we are to make no compromise with evil. We are not to unite with the rebellious and call this charity. God requires His people in this age of the world to stand for the right as unflinchingly as did John in opposition to soul-destroying errors. (AA 554.3) MC VC
