Gal 6:13   For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh.

These Jews couldn't keep God's Law before Christ either, as the examples from The Word are plentiful. Self-righteousness and pride was their game on these Galatians.

Gal 6:14   But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by Whom the world is crucified unto me, and I unto the world.

     One who is truly in Christ, understanding the position and value of the flesh compared to Christ's Spirit are very glad to know that the 'flesh' things are going to perish. "Well how can that be, I mean we're still in the flesh, and God made us flesh didn't He?" Yes, He did, and we each have a Mission in the flesh; but didn't you know that He made us 'spirit' first, before He made us flesh? How did your 'soul' get into this flesh? The 'flesh' did not enter the 'soul', or spiritual body. As our Father even told us with the man Adam in Genesis 2:7, He breathed into the nostrils of Adam, and man became a 'living soul', in the flesh. To be in Christ is to 'remember' that time 'of old'(First Earth age) with our Father and His Son, not of flesh, but in Spirit.
     I'm surprised at how so many who have faith in Christ can admit their belief in a future Kingdom of Spirit through Christ, without the flesh, but they can't understand how that Kingdom of Spirit did at one time exist, before this flesh age (see my Genesis Letters). This is how Paul can say that this world of flesh is crucified to him, and he unto the world. The good things of this earth, setup by our Father in the beginning, will remain.

 

 2 Peter 3: Read All.

Gal 6:15   For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.

     To be in Christ, with understanding of His future Kingdom upon this earth and the type of Kingdom It will be, is to be a 'new creature'. The things of this old flesh world will just begin to lose our interest as we focus on this future Kingdom in Christ. Then all those fancy things of the world become; "Oh yeah, that's a really nice sports car, good workmanship and skilfully done, but... uh, I don't really need it." Fads of the day just go out the window. Then it becomes so much easier to appreciate the really good things our Father has given us in this life, things not built by man's hands. And we become more focused upon the needs of others who are in a much worse state than us.

Gal 6:16   And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God.
17    From henceforth let no man trouble me: for I bear in my body the marks of the Lord Jesus.
18    Brethren, the grace of our Lord Jesus Christ be with your spirit. Amen.

 

     Those who love our Father and His Son, who have a close walk with Him, are the True Israel of God. And that means all peoples, regardless of nationality or race, if... we walk in Christ.
     Paul is talking about the 'marks' (stigma) he received from men as punishment for staying true to Christ, preaching His Word, and not being a 'man pleaser'.  He gave us a clue as to his personal sufferings for Christ in,

 

 2 Cor.11:23-29: Read All.

 

He was weary from his work in Christ, but he never gave up, regardless of the punishment. What an example he set for us today, and especially in these times, yet, Christ Jesus gave a better Example, being crucified on the cross for us.

     We are very close to Christ's return friends. His Kingdom everlasting is just around the corner. But a false 'one-world kingdom' upon this earth must first try and imitate Christ's True Kingdom. That false kingdom of the 'New World Order' is in the final stages today.
