Pseudo Christian Or New Creation?

Galatians 6:11-18 (NASB)
¹¹  See with what large letters I am writing to you with my own hand.
¹²  Those who desire to make a good showing in the flesh try to compel you to be circumcised, simply so that they will not be persecuted for the cross of Christ.
¹³  For those who are circumcised do not even keep the Law themselves, but they desire to have you circumcised so that they may boast in your flesh.
¹⁴  But may it never be that I would boast, except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world.
¹⁵  For neither is circumcision anything, nor uncircumcision, but a new creation.
¹⁶  And those who will walk by this rule, peace and mercy be upon them, and upon the Israel of God.
¹⁷  From now on let no one cause trouble for me, for I bear on my body the brand-marks of Jesus.
¹⁸  The grace of our Lord Jesus Christ be with your spirit, brethren. Amen.

1.     Don’t Impersonate A Christian Become One

2.     Don’t Brag About Yourself Boast In The Cross Of Christ

Galatians 5:1 (NASB)
¹  It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery.
