Psalms 84:6

The ordinances of God are the believer's solace in this evil world; in them he enjoys the presence of the living God: this causes him to regret his absence from them. They are to his soul as the nest to the bird. Yet they are only an earnest of the happiness of heaven; but how can men desire to enter that holy habitation, who complain of Divine ordinances as wearisome? Those are truly happy, who go forth, and go on in the exercise of religion, in the strength of the grace of Jesus Christ, from whom all our sufficiency is. The pilgrims to the heavenly city may have to pass through many a valley of weeping, and many a thirsty desert; but wells of salvation shall be opened for them, and consolations sent for their support. Those that press forward in their Christian course, shall find God add grace to their graces. And those who grow in grace, shall be perfect in glory.

Who passing through the valley of Baca make it a well. Traversing joyfully the road to the great assembly, the happy pilgrims found refreshment even in the dreariest part of the road. As around a well men meet and converse cheerfully, being refreshed after their journey, so even in the vale of tears, or any other dreary glen, the pilgrims to the skies find sweet solace in brotherly communion and in anticipation of the general assembly above, with its joys unspeakable. Probably there is here a local allusion, which will never now be deciphered, but the general meaning is clear enough. There are joys of pilgrimage which make men forget the discomforts of the road. "The rain also filleth the pools." God gives to his people the supplies they need while traversing the roads which he points out for them. Where there were no natural supplies from below, the pilgrims found an abundant compensation in waters from above, and so also shall all the sacremental host of God's elect. Ways, which otherwise would have been deserted from want of accommodation, were made into highways abundantly furnished for the travellers' wants, because the great annual pilgrimages led in that direction; even so, Christian converse and the joy of united worship makes many duties easy and delightful which else had been difficult and painful.
