matthew 5:10 Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven. - Free Bible Online

      10. Blessed are they which are persecuted for righteousness' sake, &c.--How entirely this final beatitude has its ground in the Old Testament, is evident from the concluding words, where the encouragement held out to endure such persecutions consists in its being but a continuation of what was experienced by the Old Testament servants of God. But how, it may be asked, could such beautiful features of character provoke persecution? To this the following answers should suffice: "Every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved." "The world cannot hate you; but Me it hateth, because I testify of it, that the works thereof are evil." "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." "There is yet one man (said wicked Ahab to good Jehoshaphat) by whom we may inquire of the Lord: but I hate him; for he never prophesied good unto me, but always evil" (Joh 3:20; 7:7; 15:19; 2Ch 18:7). But more particularly, the seven characters here described are all in the teeth of the spirit of the world, insomuch that such hearers of this discourse as breathed that spirit must have been startled, and had their whole system of thought and action rudely dashed. Poverty of spirit runs counter to the pride of men's heart; a pensive disposition, in the view of one's universal deficiencies before God, is ill relished by the callous, indifferent, laughing, self-satisfied world; a meek and quiet spirit, taking wrong, is regarded as pusillanimous, and rasps against the proud, resentful spirit of the world; that craving after spiritual blessings rebukes but too unpleasantly the lust of the flesh, the lust of the eye, and the pride of life; so does a merciful spirit the hard-heartedness of the world; purity of heart contrasts painfully with painted hypocrisy; and the peacemaker cannot easily be endured by the contentious, quarrelsome world. Thus does "righteousness" come to be "persecuted." But blessed are they who, in spite of this, dare to be righteous.
      for theirs is the kingdom of heaven--As this was the reward promised to the poor in spirit--the leading one of these seven beatitudes--of course it is the proper portion of such as are persecuted for exemplifying them.
