Psalms 122:6

Here, I. David calls upon others to which well to Jerusalem, Psa 122:6, Psa 122:7. Pray for the peace of Jerusalem, for the welfare of it, for all good to it, particularly for the uniting of the inhabitants among themselves and their preservation from the incursions of enemies. This we may truly desire, that in the peace thereof we may have peace; and this we must earnestly pray for, for it is the gift of God, and for it he will be enquired of. Those that can do nothing else for the peace of Jerusalem can pray for it, which is something more than showing their good-will; it is the appointed way of fetching in mercy. The peace and welfare of the gospel church, particularly in our land, is to be earnestly desired and prayed for by every one of us. Now, 1. We are here encouraged in our prayers for Jerusalem's peace: Those shall prosper that love thee. We must pray for Jerusalem, not out of custom, nor for fashion's sake, but out of a principle of love to God's government of man and man's worship of God; and, in seeking the public welfare, we seek our own, for so well does God love the gates of Zion that he will love all those that do love them, and therefore they cannot but prosper; at least their souls shall prosper by the ordinances they so dearly love. 2.
