For it is as it were a doctrine, that no one receives a divine gift, who seeks not for it. Even the Saviour Himself is commanded by the Father to ask, that He may give it Him, as we read, Require of Me, and I will give Thee the heathen for Thine inheritance. (Ps. 2:8) And our Saviour Himself says, Ask, and it shall be given you. (Luke 11:9) Wherefore He says here emphatically, Thou wouldest have asked of Him, and He would have given thee.
