Main point summary
It is vital to remember that the cross of Jesus Christ is our only ground of boasting and our only distinguishing mark .
See with what large letters I am writing to you j with my own hand.
k It is those who want to make a good showing in the flesh l who would force you to be circumcised,
and only m in order that they may not be persecuted for the cross of Christ.
For even those who are circumcised do not themselves keep the law,
but they desire to have you circumcised
that they may boast in your flesh .
But far be it from me to boast
n except in the cross of our Lord Jesus Christ,
by which 1 the world o has been crucified to me,
and I to the world.
For p neither circumcision counts for anything,
but q a new creation.
And as for all who walk by this rule, r peace and mercy be upon them,
and upon s the Israel of God.
From now on let no one cause me trouble,
for I bear on my body the marks of Jesus.
t The grace of our Lord Jesus Christ be u with your spirit, brothers. Amen.
The Judaizers focus on outward appearance in order to avoid persecution; this is law-breaking.
But Paul will boast only in the cross, because the new creation is the only thing that matters.
Paul emphasizes that the only marks that matter are those caused by suffering for the cross.
Paul may be referring to the Judaizers here.
