Jesus took on sinful flesh:
Rom 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
If Jesus flesh was not of the ability to sin then He wasn't given sinful flesh. Additionally, it says that Jesus condemned sin in the flesh. This would obviously include His own flesh. So this means that somehow Jesus had to condemn sin in His own flesh. Therefore, desires that could result in sin must arise in His heart that He was able to subdue via the Spirit before it could become sin.
Paul

AMEN Paul. What makes it so hard to see is not understanding that the Son/Seed He sent was SPIRIT, as each Seed bears fruit after it's OWN KIND, and the Father is a Spirit who bears Spirit Seed.
This Seed came in the likeness of sinful flesh (flesh man Jesus), or another way to say it, is that it too was lowered into this bondage of corruption, which is what sinful flesh IS.
It is this SPIRIT SEED that was given Him in the womb, the wheat that is raised up TOGETHER with the tares in the field of Matt. 13 that is the natural man, that OVERCOMES the tares/sinful flesh. This is the anointing from within.
This is why He overcame sin IN THE FLESH, beginning with His own. This Seed is He who both DESCENDED (into flesh beginning with the man Jesus) and ASCENDED (back to origination point) back to the glory that He had before.
We too, were as spirits lowered into flesh/bondage of corruption, but He subjected the same in hope, ie. Christ/Spirit Seed in you, hope of glory/ascending back to origination point.
When He received the anointing from without (dove), then His ministry began. In like fashion, when we receive the baptism in the HG which does the WORKS, our ministry to the body should begin.
If you add the anointing from within with the anointing from without, you have inner layer of gold inside the Ark of the Covenant, followed by the outer layer of gold, both of which cover the "sheetim" (had to change spelling because of board restrictions) wood, which is as our/his humanity.
This is the pattern and cannot be broken, He WAS/IS the PATTERN SON. Following this pattern brings us to Romans 8 talking about the SONS of God who are going to be manifested, yet He is called the ONLY BEGOTTEN SON OF GOD.
Only begotten means THERE'S ONLY ONE, but He became a many membered body which is SPIRIT, ie. a HARVEST from the ONE SEED.
And He did say when you've seen ME you've seen the Father, but the '"me" there was the Spirit/Seed that came from the Father, and therefore was the express image of the Father.
This is the revelation upon which He builds His church, ie. Peter flesh and blood (not even His) have revealed this to you, but your Father which is in heaven. What was revealed?
Thou art the Christ/Spirit Seed/Anointed one. In other words, WHO is it you hear talking to you, Peter? This is why we are told that hereafter we'll not know Him after the flesh but after the Spirit.
The flesh of Him is "gone" in that it was consumed from the glory which was within, ie. MORTALITY covered up of IMMORTALITY, which is the PATTERN.
He was given pre-eminence as the FIRSTBORN of many brethren. He was not firstborn of the FLESH! He was firstborn of the SPIRIT!
Name denotes nature and there is no other NATURE under heaven like this name/nature, BY WHICH WE ARE SAVED, from this bondage of corruption we have been lowered into.
In My Father's house are many mansions. In the older Strong's 'mansions' there runs into a meaning of "nests". The booths of the feast of Tabernacles are as NESTS. They are 'nests' for the overcoming 'eagles'. He goes to prepare a place for us, that where He is, we might be also.
Where is He and how did He get there? The pattern is above. Blessings....
