5 Therefore let the Son do the works of Him That sent Him, and the Father also do the works of the Son. “At all events,” you say, “the Father wills, the Son executes.” Lo, I show, that the Son wills, and the Father executes. Do you say, “where do you show this?” I show it at once. “Father, I will.” Now here if I had a mind to cavil, lo, the Son commands, and the Father executes. What will You? “That where I am, they may be also with Me.” We have escaped, there shall we be, where He is; there shall we be, we have escaped.
Who can undo the “I Will” of the Almighty? You hear the will of His power, hear now the power of His will. “As the Father” says He “raises up the dead and quickens them; even so the Son quickens whom He will.” “Whom He will.” Say not, The Son quickens them, whom the Father commands Him to quicken. “He quickens whom He will.” So then whom the Father will, and whom Himself will: because where there is One Power, there is One Will. Let us then in a heart blind no more hold fast that the Nature of the Father and the Son is One and the Same; because the Father is very Father, the Son is very Son. What He is, That did He beget: because the Begotten was not degenerate.
