In that day you will no longer ask Me anything. Truly, truly, I tell you, whatever you ask the Father in My name, He will give you.
In that day--of the dispensation of the Spirit (as in Joh 14:20). ye shall ask--inquire of me nothing--by reason of the fulness of the Spirit's teaching (Joh 14:26; Joh 16:13; and compare Jo1 2:27).
The disciples were so blocked by their own ignorance that every word of Christ stumbled them, like children learning their letters. But the Spirit would enlighten them to move freely through the deepest mysteries of God without hindrance, needing no more those endless questions that now held them back.

While I was with them, they came directly to me for help and instruction, dependent on my bodily presence. Now they must address their requests to the Father in my name, and through my Spirit's influence I will make known what I would do if I stood before them still.
