Galatians 5:11
But, brothers, if I were still preaching [that a person had] to be circumcised, why am I being persecuted? [Note: Paul's argument seems to be "I must not be preaching circumcision since I am being persecuted by those who believe in it"]. [If I preached that a person had to be circumcised] then my preaching that Christ died on the cross would not be such an offense [to those who believe in it].

See 3:1-3].

shouting, "[You] Israelites, help [us]! This man is teaching people everywhere [to be] against our people [i.e., the Jews], the law of Moses and this place [i.e., the Temple]; and in addition to that he has also brought Greeks [i.e., Gentiles] into the Temple and has [thereby] contaminated this holy place."

Romans 9:32-33
Why? Because they did not [attempt to do it] by faith [in Him], but by trying to fulfill all the requirements [of the law]. So, they stumbled over "the stumbling stone," [i.e., the Jews refused to become obedient to Christ. See I Pet. 2:6-8].
1 Corinthians 1:18
For the message of [Christ dying on] the cross is foolishness to those who are perishing [i.e., in a lost state], but it is God's power to us who are being saved.

[And it also says, Isa. 8:14, that He would be], "A stone that people would stumble over and a rock over which they would trip and fall." The way they stumble is by disobeying the Gospel message. They were destined [though not forced] to do this.
