Charles H. Spurgeon on Psalms 107:37

And sow the fields, and plant vineyards, which may yield fruits of increase. Men work when God works. His blessing encourages the sower, cheers the planter, and rewards the labourer. Not only necessaries but luxuries are enjoyed, wine as well as corn, when the heavens are caused to yield the needed rain to fill the watercourses. Divine visitations bring great spiritual riches, foster varied works of faith and labours of love, and cause every good fruit to abound to our comfort and to God's praise. When God sends the blessing it does not supersede, but encourages and develops human exertion. Paul plants, Apollos waters, and God gives the increase.
