3-е Иоанна 1:11

Follow not that which is evil - Μμ μιμου το κακον· Do not imitate that wicked man, i.e., the conduct of Diotrephes; be merciful, loving, and kind. For whatever profession any man may make, it will ever appear that he who doeth good is of God - he alone is the person who uses rightly the grace received from God, and he alone shall enjoy the Divine approbation; While he that doeth evil - He who is unfeeling, unmerciful, unkind, hath not seen God - has no proper knowledge of that God whose Name is mercy, and whose Nature is love.

follow not that which is evil--as manifested in Diotrephes (Jo3 1:9-10). but . . . good--as manifested in Demetrius (Jo3 1:12). is of God--is born of God, who is good. hath not seen God--spiritually, not literally.

Beloved, follow not that which is evil,.... Follow not evil in general, it being hateful to God, contrary to his nature and will, and bad in itself, as well as pernicious in its consequences; and particularly follow not, or do not imitate the particular evil or evils in Diotrephes; as his pride, ambition, love of preeminence, and tyrannical government in the church, and especially his hard heartedness, cruelty, and inhospitality to the poor saints; and so the Arabic version reads, "do not imitate him in evil"; the examples of persons in office and authority have great influence, especially in cases of charity, when men can be excused thereby, and save their money, or be freed from an expense: but that which is good; follow and imitate that, be a follower of God, imitate him in acts of kindness and beneficence, be merciful as he is; copy the deeds of Jesus Christ, who went about doing good, and declared it to be more blessed to give than to receive; and tread in the steps of those good men, who have shown love to the name of Christ, by ministering to his saints; for though the apostle may mean everything that is good, which is to be followed and imitated in any, yet he chiefly designs acts of kindness and beneficence to poor saints and ministers: to which he encourages by the following, he that doeth good is of God; he is a child of God, he appears to be so, in that he is like to his heavenly Father, who is kind and merciful; he is born of God, he is passed from death to life, which his love to the brethren shows; he has the grace of God, and strength from Christ, and the assistance of the Spirit, without either of which he could not do that which is good: but he that doeth evil hath not seen God; has had no spiritual saving sight of God in Christ; for if he had, he woul…

In this epistle the apostle congratulates Gaius upon the prosperity of his soul (Jo3 1:1, Jo3 1:2), upon the fame he had among good Christians (Jo3 1:3, Jo3 1:4), and upon his charity and hospitality to the servants of Christ (Jo3 1:5, Jo3 1:6). He complains of contemptuous treatment by an ambitious Diotrephes (Jo3 1:9, Jo3 1:10), recommends Demetrius (Jo3 1:12), and expresses his hope of visiting Gaius shortly (Jo3 1:13, Jo3 1:14).

1:11 those who do evil: Diotrephes was condemned for his failure to live by the Christian rule of love (1 Jn 3:10-14). This was how Gaius could be sure that Diotrephes was not living according to the truth. This applies to all who refuse to accept the apostolic teaching about Jesus Christ and refuse to live in fellowship with others who do.
