Covenant theology glorifies God alone. There are other theologies abroad which magnify men; they give him a finger in his own salvation, and so leave him a reason for throwing up his cap and saying, “Well done I;” but covenant theology puts man aside, and makes him a debtor and a receiver. It does, as it were, plunge him into the sea of infinite grace and unmerited favour, and it makes him give up all boasting, stopping the mouth that could have boasted by filling it with floods of love, so that it cannot utter a vainglorious word. A man saved by the covenant must give all the glory to God’s holy name, for to God all the glory belongs. In salvation wrought by the covenant the Lord has exclusive glory.
Charles Spurgeon
