Paul’s method was also incarnational, we see that in 1 Cor 9:19 – 23:

“When I was with the Jews, I lived like a Jew to bring the Jews to Christ. When I was with those who follow the Jewish law, I too lived under that law. Even though I am not subject to the law, I did this so I could bring to Christ those who are under the law. When I am with the Gentiles who do not follow the Jewish law, I too live apart from that law so I can bring them to Christ. But I do not ignore the law of God; I obey the law of Christ. When I am with those who are weak, I share their weakness, for I want to bring the weak to Christ. Yes, I try to find common ground with everyone, doing everything I can to save some. I do everything to spread the Good News and share in its blessings.”

He engaged culture for the sake of the Gospel.
