Paul’s purpose in this epistle is to show Christians that these sublime and divine mysteries—that is, God’s actual divine essence and his will, administration and works—are absolutely beyond all human thought, human understanding or wisdom; in short, that they are and ever will be incomprehensible, inscrutable and altogether hidden to human reason. When reason presumptuously undertakes to solve, to teach and explain these matters, the result is worthless, yea, utter darkness and deception. If anything is to be ascertained, it must be through revelation alone; that is, the Word of God, which was sent from heaven.
