John 7:29

Ver. 29. To the ignorance of God with which He charges the Jews, Jesus opposes the intimate consciousness which He Himself has of God and of His true relation to Him. This relation is, first of all, a relation of essence (εἰμί, I am, I proceed from Him). In fact, this first clause cannot refer to the mission of Jesus which is expressly mentioned in the following one. Jesus affirms that He knows God, first by virtue of a community of essence which unites Him to Him. The second clause does not depend on the word because. It is an affirmation, which serves also to justify His claim to know God. The one sent has intimate communion with Him who sends Him, and consequently must know Him. Hence it follows that Jesus is the Messiah, and that in a sense much more exalted than that which the Jews attributed to this office.
