Even while doing the will of God, you will face opposition

Acts 13:42–52

“So when the Jews went out of the synagogue, the Gentiles begged that these words might be preached to them the next Sabbath.
Now when the congregation had broken up, many of the Jews and devout proselytes followed Paul and Barnabas, who, speaking to them, persuaded them to continue in the grace of God.
On the next Sabbath almost the whole city came together to hear the word of God.
But when the Jews saw the multitudes, they were filled with envy; and contradicting and blaspheming, they opposed the things spoken by Paul.
Then Paul and Barnabas grew bold and said, ‘It was necessary that the word of God should be spoken to you first; but since you reject it, and judge yourselves unworthy of everlasting life, behold, we turn to the Gentiles.
For so the Lord has commanded us: “I have set you as a light to the Gentiles, that you should be for salvation to the ends of the earth.”’
Now when the Gentiles heard this, they were glad and glorified the word of the Lord. And as many as had been appointed to eternal life believed.
And the word of the Lord was being spread throughout all the region.
But the Jews stirred up the devout and prominent women and the chief men of the city, raised up persecution against Paul and Barnabas, and expelled them from their region.
And they shook off the dust from their feet against them, and came to Iconium.
And the disciples were filled with joy and with the Holy Spirit.”

John 16:33

“These things I have spoken to you, that in Me you may have peace. In the world you will have tribulation; but be of good cheer, I have overcome the world.”

Ephesians 6:12

“For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.”

Colossians 2:15

“Having disarmed principalities and powers, He made a public spectacle of them, triumphing over them in it.”
