Pray for the peace of Jerusalem. Peace was her name, pray that her condition may verify her title. Abode of Peace, peace be to thee. Here was a most sufficient reason for rejoicing at the thought of going up to the house of the Lord, since that sacred shrine stood in the centre of an area of peace: well might Israel pray that such peace should be continued. In a church peace is to be desired, expected, promoted, and enjoyed. If we may not say "Peace at any price, "yet we may certainly cry "Peace at the highest price." Those who are daily fluttered by rude alarms are charmed to reach their nest in a holy fellowship, and abide in it. In a church one of the main ingredients of success is internal peace: strife, suspicion, party spirit, division, —these are deadly things. Those who break the peace of the church deserve to suffer, and those who sustain it win a great blessing. Peace in the church should be our daily prayer, and in so praying we shall bring down peace upon ourselves; for the Psalmist goes on to say, They shall prosper that love thee, or, perhaps we may read it as a prayer, "May they have peace that love thee." Whether the passage be regarded as a promise or as a prayer matters not, for prayer pleads the promise, and the promise is the ground of prayer. Prosperity of soul is already enjoyed by those who take a deep interest in the church and cause of God: they are men of peace, and find peace in their holy endeavours: God's people pray for them, and God himself delights in them. Prosperity of worldly condition often comes to the lovers of the church if they are able to bear it: many a time the house of Obededom is blessed because of the ark of the Lord. Because the Egyptian midwives feared the Lord, therefore the Lord made them houses. No man shall ever be a permanent loser by the house of the Lord: in peace of heart alone. If in nothing else, we find recompense enough for all that we can do in promoting the interests of Zion.
