John Calvin was right when he pegged the human heart an idol factory. We can manufacture a stream of objects in which we put our trust instead of the true and living God.
Matthew Henry shows us just how easy it is to multiply our idols:
“Pride makes a god of self, covetousness makes a god of money, sensuality makes a god of the belly; whatever is esteemed or loved, feared or served, delighted in or depended on, more than God, that (whatever it is) we do in effect make a god of.”*
