John Chrysostom
So that the apostles would not think they accomplished everything by themselves, God permitted them to be persecuted. Two goods came from this.
They did not become high-minded, as though overcoming everything by themselves. At the same time, they did not fear as though they were guilty of anything.
Thus it also happened by divine ordering that they were summoned from place to place.
See how persecutions everywhere serve the spread of the preaching. "And many of them," it says, "believed, and not a few of the honorable Greek women and men" (Acts 17:12).
But the Jews opposed them.
Why then did the one who said, "We should go to the Gentiles, and they to the circumcised" (Gal 2:9), converse with the Jews?
He did this from an abundance of zeal.

But if it was necessary to converse with the Jews too, why did he again say, "He who worked through Peter for the apostleship to the circumcised worked also through me for the Gentiles" (Gal 2:8)?
As those apostles conversed with the Gentiles, though they had been sent to the circumcised, so he conversed more with the Gentiles. Yet he did not abandon the Jews, lest they seem to have divided themselves.
But why, you ask, did they not remain here? Why did they not work signs?
If Paul remained for some time where he had been stoned, much more could he have remained here. Why did he not?
It was not God's will that they should constantly work signs. If, when persecuted, they conquer without signs, this is no lesser sign than working signs.
As God now conquers without signs, so He often deigned to conquer then also.
The apostles did not resort to signs. As Paul says, "We preach Christ crucified" (1 Cor 1:23).
To those who seek signs and wisdom, we communicate that by which another could not persuade even with the help of signs, and yet we persuade.
