Matthew Henry's Concise Commentary

8:18-23 When God comes towards us in ways of mercy, we must meet him with joy and thankfulness. Therefore be faithful and honest in all your dealings; and let it be a pleasure to you to be so, though thereby you come short of the gains others get dishonestly; and, as much as in you lies, live peaceably with all men. Let the truths of God rule in your heads, and let the peace of God rule in your hearts. Thus the ancient servants of God drew the notice of heathen neighbours, whose prejudices were softened. A great increase to the church shall be made. Hitherto the Jews had been prone to learn the idolatries of other nations: what more unlikely than that they should teach religion to their conquerors, and to all the principal nations of the earth! Yet this is expressly foretold, and it came to pass. Hitherto the prophecy has been wonderfully fulfilled, and no doubt future events will explain it further. It is good to be with those who have God with them; if we take God for our God, we must take his people for our people, and be willing to take our lot with them. But let not any one think that mere zeal, either for Jews or Gentiles, will stand in the place of personal religion. Let us be living epistles of Christ, known and read of all men, so that others may wish to go with us, and to have their portion with us in the realms of bliss.
