1 When the Holy Gospel was being read, we heard what in truth ought at once to put every earnest soul in motion to seek, not to faint. For whoso is not moved, is not changed. But there is a dangerous movement, of which it is written, “Suffer not my feet to be moved.” But there is another movement of him who seeks, knocks, asks. What then has been read we have all heard; but I suppose we have not all understood. It makes mention of that which together with me ye should seek, with me ask, for the receiving of which you should with me knock.
For as I hope the grace of the Lord will be with us, that whereas I wish to minister to you, I too may be thought worthy to receive. What is it, I pray you, that we have just heard that the Lord said to His disciples? “Hitherto have ye asked nothing in My Name.” Is He not speaking to those disciples, who, after He had sent them, having given them power to preach the Gospel, and to do mighty works, returned with joy, and said to Him, “Lord, even the devils are subject unto us through Your Name”? You recognise, you recollect this which I have quoted from the Gospel, which in every passage and every sentence speaks truth, nowhere false, nowhere deceives.
How then is it true, “Hitherto have ye asked nothing in My Name”? And, “Lord, even the devils are subject unto us through Your name”? Of a surety this puts the mind in motion to ascertain the secret of this difficulty. Therefore ask we, seek, knock. Be there in us faithful godliness, not a restlessness of the flesh, but a submission of the mind, that He who sees us knocking may open unto us.
