This is really not that hard to understand if you use the Torah rightly divided and make sure all lines up with it. According to the law of the seed, all seeds bear fruit after their own kind. Father, being a Spirit, therefore can only bear fruit after His own kind and His own kind must therefore be a SPIRIT SEED. This seed was enrobed in the flesh of Yeshua, but as Yeshua said many times in many ways, He was not Father, but Father's Seed.
This is why He said when you've seen ME (the Spirit Seed), you've seen the Father. And why He told Peter that His response as to who He was not only accurate, but that it could only be revealed by the Father who is Spirit, that flesh and blood did not and could not reveal it him, and that includes the flesh of Yeshua. This is the dividing asunder of flesh and Spirit and it must be done even with Yeshua.
This is also why when Paul got knocked off his high horse HE SAW NO MAN, yet the Lord told Paul he was persecuting His body. How do you persecute the person standing in front of you if He is Spirit, except it be that He was referring to His body which also must be Spirit, in the believers? This is why the GOOD SEED in Matt. 13 is mentioned, is planted in a field. We are that field/earthen vessel He is planted in. Blessings....
