2 Chronicles 12:9,10

Instead of which king Rehoboam made shields of brass.

The downward grade

See how deterioration follows all character that goes down in its religious aspects. This deterioration marks the whole progress of human development. Is it not so with regard to all personal service? How ardent we once were! How devoted to the house of God, how punctual in attendance, how zealous in worship! How we longed for the hour of praise to double itself, that we might have long intercourse with the Father and the Son and the Holy Ghost! Now how soon we become uneasy, how we long to be released, how patience becomes sensitive, and yields in angry surrender because too much tried! You never bring gold for brass when you leave God. The prodigal never brings any treasure back with him. When men go away intellectually from the Bible they bring back brass for gold. When they leave the Bible morally they bring back brass for gold. When they leave sympathetically they bring back artifice for inspiration, mechanics for vital communion. (J.Parker, D.D.)
