"The people of the city were divided; some sided with the Jews, others with the apostles." NIV translation
In the last verse, we saw that God showed what side he was on in this situation. Therefore, the division in the city was between God's people and those that are being disobedient. The same is true in our cities and countries today.
"There was a plot afoot among the Gentiles and Jews, together with their leaders, to mistreat them and stone them." NIV translation
The gospel of Jesus Christ was not a popular message, especially among the religious leaders of the time. Therefore, they plotted to hurt the apostles just as they had done to Jesus himself.
The same situation exists today in most of the world but we have comfort in the fact that God is with us.
"But they found out about it and fled to the Lycaonian cities of Lystra and Derbe and to the surrounding country, where they continued to preach the good news." NIV translation
God takes care of his own. We are not told of how Paul and Barnabas learned of the plot only that they were able to avoid it. They went to another area and continued to share the gospel. Our first thought may be to stay and argue in the face of the opposition but Paul had proclaimed the message of Jesus Christ and it was up to God to change the people's hearts and minds. It is a good reminder to us that our "job" is merely to share the Word and that God is the one who draws them to him.
"In Lystra, there sat a man crippled in his feet, who was lame from birth and had never walked. He listened to Paul as he was speaking. Paul looked directly at him, saw that he had faith to be healed and called out,'Stand up on your feet!' At that, the man jumped up and began to walk." NIV translation
In this passage, God worked through Paul to heal a man that had been crippled all of his life. There are many "faith healers" today that basically say that anyone can be healed (for a price) but we see here that Paul "saw that he had faith to be healed". Therefore, we can assume that there were people who did not have the faith to be healed. We might also note that Paul did not ask for anything in return either before or after the man was healed.
