Charles H. Spurgeon on Psalms 107:34

A fruitful land into barrenness. This has been done in many instances, and notably in the case of the psalmist's own country, which was once the glory of all lands and is now almost a desert. For the wickedness of them that dwell therein. Sin is at the bottom of sorrow. It first made the ground sterile in father Adam's day, and it continues to have a blighting effect upon all that it touches. If we have not the salt of holiness we shall soon receive the salt of barrenness, for the text in the Hebrew is —"a fruitful land into saltness." If we will not yield the Lord a harvest of obedience he may forbid the soil to yield us a harvest of bread, and what then? If we turn good into evil can we wonder if the Lord pays us in kind, and returns our baseness into our own bosoms? Many a barren church owes its present sad estate to its inconsistent behaviour, and many a barren Christian has come into this mournful condition by a careless, unsanctified walk before the Lord. Let not saints who are now useful run the risk of enduring the loss of their mercies, but let them be watchful that all things may go well with them.
