6 The disciples then of the Lord Jesus Christ while yet under the Law had to be cleansed still, to be nourished still, to be corrected still, to be directed still. For they still had concupiscence; whereas the Law says, “You shall not lust.” Without offense to those holy rams, the leaders of the flock, without offense to them I would say it, for I say the truth: the Gospel relates, that they contended which of them should be the greatest, and while the Lord was yet on earth, they were agitated by a dissension about pre-eminence. Whence was this, but from the old leaven?
Whence, but from the law in the members, resisting the law of the mind? They sought for eminence; yea, they desired it; they thought which should be the greatest; therefore is their pride put to shame by a little child. Jesus calls unto him the age of humility to tame the swelling desire. With good reason then when they returned too, and said, “Lord, behold even the devils are subject unto us through Your Name.” (It was for a nothing that they rejoiced; of what importance was it compared to that which God promised?)
The Lord, the Good Master, quieting fear, and building up a firm support, said to them, “In this rejoice not that the devils are subject unto you.” Why so? Because “many will come in My Name, saying, Behold, in Your Name we have cast out devils; and I will say to them, I know you not. In this rejoice not, but rejoice because your names are written in heaven.” You cannot yet be there, yet notwithstanding you are already written there. Therefore “rejoice.” So that place again, “Hitherto have ye asked nothing in My Name.” For what you have asked, in comparison with that which I am willing to give, is nothing.
For what have ye asked in My Name? That the devils should be subject unto you? “In this rejoice not,” that is, what you have asked is nothing; for if it were anything, He would bid them rejoice. So then it was not absolutely nothing, but that it was little in comparison of that greatness of God's rewards. For the Apostle Paul was not really not anything; and yet in comparison of God, “Neither is he that plants anything, neither he that waters.” And so I say to you, and I say to myself, both to myself and you I say, when we ask in Christ's Name for these temporal things.
For you have asked undoubtedly. For who does not ask? One asks for health, if he is sick; another asks for deliverance, if he is in prison; another asks for the port, if he is tossed about at sea; another asks for victory, if he is in conflict with an enemy; and in the Name of Christ he asks all, and what he asks is nothing. What then must be asked for? “Ask in My Name.” And He said not what, but by the very words we understand what we ought to ask. “Ask, and you shall receive, that your joy may be full.
Ask, and you shall receive, in My Name.” But what? Not nothing; but what? “That your joy may be full;” that is, ask what may suffice you. For when you ask for temporal things, you ask for nothing. “Whoso shall drink of this water, shall thirst again.” He lets down the watering pot of desire into the well, he takes up whereof to drink, only that he may thirst again. “Ask, that your joy may be full;” that is, that you may be satisfied, not feel delight only for a time. Ask what may suffice you; speak Philip's language, “Lord, show us the Father, and it suffices us.” The Lord says to you, “Have I been so long time with you, and have ye not known Me?
Philip, he that sees Me, sees the Father also.” Render then thanks to Christ, made weak for you that are weak, and make ready your desires for Christ's Divinity, to be satisfied therewith. Turn we to the Lord, etc.
