Zechariah Chapter 8
(Zac 8:1-8) The restoration of Jerusalem.
(Zac 8:9-17) The people encouraged by promises of God's favour, and exhorted to holiness.
(Zac 8:18-23) The Jews in the latter days.
The sins of Zion were her worst enemies. God will take away her sins, and then no other enemies shall hurt her. Those who profess religion must adorn their profession by godliness and honesty. When become a city of truth and a mountain of holiness, Jerusalem is peaceable and prosperous. Zac 8:4, Zac 8:5, beautifully describe a state of great outward peace, attended with plenty, temperance, and contentment. The scattered Israelites shall be brought together from all parts. God will never leave nor forsake them in a way of mercy, for this he has promised them; and they shall never leave nor forsake him in a way of duty, as they have promised him. These promises were partly fulfilled in the Jewish church, betwixt the captivity and the time of Christ's coming; and they had fuller accomplishment in the gospel church; but the full import must be as to the future times of the Christian church, or the future restoration of the Jews. With men this is impossible, but with God all things are possible; so far are God's thoughts and ways above ours. In the present low state of vital godliness, we can hardly conceive that so complete a change can be made; but a change thus extensive and glorious, can be brought to pass by the almighty power of the new-creating Spirit, in less time than he was pleased to employ in creating the world. Let the hands of all who labour in the cause of the gospel be strong, serving the Lord in true holiness, assured that their labour shall not be in vain.
Those only who lay their hands to the plough of duty, shall have them strengthened with the promises of mercy: those who avoid their fathers' faults have the curse turned into a blessing. Those who believed the promises, were to show their faith by their works, and to wait the fulfilment. When God is displeased, he can cause trade to decay, and set every man against his neighbour; but when he returns in mercy, all is happy and prosperous. Surely believers in Christ must not trifle with the exhortation to put away lying, and to speak every man peace with his neighbour, to hate what the Lord hates, and to love that wherein he delights.
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.
