Lastly, Observe what shall be the effect, and what the cause, of this wonderful softening and sweetening of men's tempers by the grace of God. 1. The effect of it shall be tractableness, and a willingness to receive instruction: A little child shall lead those who formerly scorned to be controlled by the strongest man. Calvin understands it of their willing submission to the ministers of Christ, who are to instruct with meekness and not to use any coercive power, but to be as little children, Matt. xviii. 3. See 2 Cor. viii. 5. 2. The cause of it shall be the knowledge of God. The more there is of that the more there is of a disposition to peace. They shall thus live in love, for the earth shall be full of the knowledge of the Lord, which shall extinguish men's heats and animosities. The better acquainted we are with the God of love the more shall we be changed into the same image and the better affected shall we be to all those that bear his image. The earth shall be as full of this knowledge as the channels of the sea are of water—so broad and extensive shall this knowledge be and so far shall it spread—so deep and substantial shall this knowledge be, and so long shall it last. There is much more of the knowledge of God to be got by the gospel of Christ than could be got by the law of Moses; and, whereas then in Judah only was God known, now all shall know him, Heb. viii. 11. But that is knowledge falsely so called which sows discord among men; the right knowledge of God settles peace.
