Seeing it is a righteous thing with God
That which is righteous in itself, is righteous in the sight of God, but it is not always so with men; men may think it a righteous thing that they should be rewarded for persecuting the followers of Christ, supposing they hereby do God good service; but on the contrary, with God, and in his sight and account, it is a righteous thing, or a point of justice,
to recompence tribulation to them that trouble you:
persecution is an affliction, or a trouble to the saints; persecutors trouble them in their minds and bodies, in their persons and property; they trouble their minds by casting reflections and reproaches upon them, by severe revilings, and cruel mockings, which all are not alike able to bear; and they trouble and afflict their bodies by imprisonment and bonds, by scourging and beating, and various cruel and torturing deaths; and they disturb them in the possession of their estates, by spoiling their goods, and confiscating them to their own use; and it is but according to "lex talionis", the law of retaliation, to render tribulation to such troublers of God's Israel; and to them it is recompensed, either in this world, or in the world to come: sometimes in this world persecutors are manifest instances of God's judgments and wrath upon them, as Herod, who stretched out his hands to vex certain of the church, killed James the brother of John, and imprisoned Peter, and was smitten by the angel of the Lord, and was eaten of worms; and the Jews, who were now the only and the implacable persecutors of the saints, in a short time had the wrath of God come upon them to the uttermost, even upon their nation, city, and temple, upon their persons and property. And if not in this life, it is a certain thing that hereafter such shall have indignation and wrath, tribulation and anguish; they shall be cast into outward darkness, into the lake of fire; and the hottest place in hell will be their portion, even devouring flames, and everlasting burnings; and are what is designed by tribulations here.
