Galatians 6:12

It is those who want to make a good showing in the flesh who would force you to be circumcised , and only in order that they may not be persecuted for the cross of Christ .

Those who want to impress people by means of the flesh are trying to compel you to be circumcised. The only reason they do this is to avoid being persecuted for the cross of Christ.

As many as desire to make a fair shew in the flesh, they constrain you to be circumcised; only lest they should suffer persecution for the cross of Christ.
