John 14:23

Vv. 23 justified the to us in the question of Judas; John 14:24 answers to: and not to the world. Between the two clauses of John 14:24, this idea must be understood: “It is not a small thing to reject my teaching; and indeed (καί) it is the teaching of God Himself” (John 12:49, etc.). Conclusion understood: “How, with such a disposition, hostile to the word both of the Son and the Father, could one be fit to become their abode!” Comp. what was said of the world in John 14:15; John 14:17.

Thus have the reasons for encouragement presented by the Lord been gradually raised one upon another: “You shall have a place secured for you with me in the Father's house....Through me, the way, you cannot fail to reach the end....Already here on earth, you have seen the Father....You shall be able to continue my work on the earth....Another divine support will give you strength for it....In this inward support, it is I myself who will join you again....The Father Himself will with me come to dwell with you....” Is there not here what may justify the: Let not your heart be troubled (John 14:1)? The following passage, which closes this first outpouring, returns to its starting-point, in that it even makes the Be not troubled, a Rejoice.
