Suffering saints have a seedness of tears. They are in tears often; they share in the calamities of human life, and commonly have a greater share in them than others. But they sow in tears; they do the duty of an afflicted state and so answer the intentions of the providences they are under. Weeping must not hinder sowing; when we suffer ill we must be doing well. Nay, as the ground is by the rain prepared for the seed, and the husbandman sometimes chooses to sow in the wet, so we must improve times of affliction, as disposing us to repentance, and prayer, and humiliation. Nay, there are tears which are themselves the seed that we must sow, tears of sorrow for sin, our own and others, tears of sympathy with the afflicted church, and the tears of tenderness in prayer and under the word. These are precious seed, such as the husbandman sows when corn is dear and he has but little for his family, and therefore weeps to part with it, yet buries it under ground, in expectation of receiving it again with advantage. Thus does a good man sow in tears. They shall have a harvest of joy. The troubles of the saints will not last always, but, when they have done their work, shall have a happy period. The captives in Babylon were long sowing in tears, but at length they were brought forth with joy, and then they reaped the benefit of their patient suffering, and brought their sheaves with them to their own land, in their experiences of the goodness of God to them. Job, and Joseph, and David, and many others, had harvests of joy after a sorrowful seedness. Those that sow in the tears of godly sorrow shall reap in the joy of a sealed pardon and a settled peace. Those that sow to the spirit, in this vale of tears, shall of the spirit reap life everlasting, and that will be a joyful harvest indeed. Blessed are those that mourn, for they shall be for ever comforted.
From Matthew Henry’s Commentary on the Whole Bible — Psalms 126:4-6
