Acts 13 introduces Paul's missionary journeys and describes the events in Antioch, Cyprus, and
Perga. As Paul and his companions moved from one area to the next, they preached without regard to Jew or Gentile. They encountered opposition most everywhere they went, Jews who tried to turn people away from the faith in Christ. But, large assemblies of Jews and God-fearing proselytes were amazed at the teaching of the Lord and believed. Acts 13:16-41 outlines the sermon that Paul preached, as to the history of their ancestors and the life and ministry of Jesus, including his death and resurrection. Paul summarizes in conclusion, " Therefore let it be know to you that through Him forgiveness of sins is proclaimed to you, and through Him everyone who believes is freed from all things, from which you could not be freed through the Law". He follows this by quoting prophesy from Habakkuk, which says that some will never believe these truths though they are clearly demonstrated to them. Next, we see an example of this fulfilled in v.45, when the Jews had heard and saw what was happening, "they were filled with jealousy and began contradicting the things spoken by Paul, and were blaspheming."
In contrast, then the Gentiles heard these things, "they began rejoicing and glorifying the Word of the Lord, as many as had been appointed to eternal life believed (v.48)". The end of this chapter in Acts describes how the Jewish leaders instigated persecution of Paul and Barnabas and drove them out of their area. But, Paul and his companions "shook off the dust of their feet" and moved on. I think there is a connection here to the prophesy from Habakkuk. Apparently, the shaking of dust from the feet represents removing further responsibility for those who refused to listen. When is it appropriate for us to do this? Do we give up on some people at some point after a time of persistent witnessing? Hmmmm. Maybe "giving up" is not the right words here, but rather we should remember that it is God who changes hearts and draws people to Himself anyway.
I don't know, but He does. What do you think?
