There are many times when the message of Christ is clearly presented that there will be resistance, even persecution, because the gospel of Christ turns religion upside down. It is as true in 2017 as in the days of the apostles of Jesus.
“Then Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles. For so hath the Lord commanded us, saying, I have set thee to be a light of the Gentiles, that thou shouldest be for salvation unto the ends of the earth. And when the Gentiles heard this, they were glad, and glorified the word of the Lord: and as many as were ordained to eternal life believed. And the word of the Lord was published throughout all the region. But the Jews stirred up the devout and honourable women, and the chief men of the city, and raised persecution against Paul and Barnabas, and expelled them out of their coasts. But they shook off the dust of their feet against them, and came unto Iconium. And the disciples were filled with joy, and with the Holy Ghost.” Acts 13:46-52 (KJV)
Paul and Barnabas were in a town where there was a Jewish synagogue, and they went there to fulfill the word of God, “To the Jew first…”. They were made bold by the power of the Holy Spirit within them and upon them.
They had shared the history of the people of Israel; reminding them of the power of God on the people, His love, His grace, His mercy; upon the people in their journey in the wilderness. All these as well with the Judges and the Kings of Israel, and how the LORD had called the Jews to be the messengers of God to the whole world.
Religion of men seeks to control men, women and children, and keeps people in bondage of sin. Christianity, following Jesus frees men, women and children from the bondage, death, and scourge of sin.
What should the messenger of Christ do when opposed by the religious elite? Do as Paul and Barnabas did. Keep on preaching, teaching, living for the Lord. “Shake the dust off your feet”, and go on doing the work of the ministry.
