John 16:3 - Joseph Benson’s Commentary on the Old and New Testaments

And these things will they do These cruelties will they exercise upon you, not because ye have done them any harm; but because they have not known the Father nor me Which, if they had done, instead of injuring me, and exercising such inhumanities toward you, my apostles, they would have received us with the greatest affection and gratitude. Here we have the true root of persecution in all its forms; it is ignorance of God and of Christ, and of the real nature of Christianity: it is a spirit that is hostile to all true piety and virtue; and our Lord here says in effect, Let this comfort you, that none will be your enemies but the worst of men. Observe, reader, 1st, Many that pretend to know God are wretchedly ignorant of him, for he that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him, 1 John 2:4. Israel of old transgressed the covenant, and yet cried, My God, we know thee. 2d, They that are ignorant of Christ cannot have any right knowledge of God. In vain do men pretend to know God and religion while they slight Christ and Christianity. 3d, Those are wretchedly ignorant of God indeed, who think it an acceptable piece of religion to persecute good people. For they that know Christ, know that he came not into the world to destroy men's lives, but to save them; that he rules by the power of truth and love, not by fire and sword. 4th, It is possible for those that are real enemies to God's service to pretend a mighty zeal for it. Satan's work has often been done in God's livery, and one of the most mischievous enemies Christianity ever had, sits in the temple of God, showing himself that he is God, 2 Thessalonians 2:4. Nay, 5th, It is common to patronise enmity to religion, with the colour of duty to God and service to his church. God's people have suffered the greatest hardships from conscientious persecutors: Paul verily thought he ought to do what he did against the name of Jesus, Acts 26:9. This, however, does not lessen the sin of persecutors, for villanies cannot be consecrated by their being acted in God's name; but it greatly increases the sufferings of the persecuted to cause them to suffer under the character of being enemies to God; but there will be a resurrection of names, as well as of bodies, at the great day.
