Galatians 5:11

but we preach Christ crucified, to Jews a stumbling block and to Gentiles foolishness,

O foolish Galatians, who bewitched you, before whose eyes Jesus Christ was publicly portrayed as crucified?

But as at that time he who was born according to the flesh was persecuting him who was born according to the Spirit, so it is now also.

Behold I, Paul, say to you that if you receive circumcision, Christ will be of no benefit to you.

And I testify again to every man who receives circumcision, that he is under obligation to keep the whole Law.

As many as are wanting to make a good showing in the flesh, these are trying to compel you to be circumcised, simply so that they will not be persecuted for the cross of Christ.

and, “A stone of stumbling and a rock of offense.” They stumble because they are disobedient to the word, and to this stumbling they were also appointed.

The one who believes in the Son of God has this witness in himself. The one who does not believe God has made Him a liar, because he has not believed in the witness which God has borne witness about His Son.
