“He who goes to and fro weeping, carrying his bag of seed, Shall indeed come again with a shout of joy, bringing his sheaves with him.” Psalm 126:6 (NASB)  Picture it.  The weeping sower.  Weeping that the precious seeds saved from last year will give a harvest this year.  Seeds need water to germinate.  Water your gospel seed with your tears.  Intercession brings harvest.  Prayerful tears can change things.  To this we can bear witness.  So, keep sowing, keep praying and keep watering.
