Paul’s infirmity of the flesh issue
Gal 4:13 Ye know how through infirmity of the flesh I preached the gospel unto you at the first.
Those who do not study the whole word tend to think that Paul had some sort of ailment which he is referring to. Well this is simply not the case at all. When we study the travels of Paul in the book of Acts we will notice that while he was visiting in Lower Galatia at Lystra some of the Jews from Antioch and Iconium stirred up the crowd against them and stoned Paul, who they left for dead. After being raised from the dead he went to Derbe the next day and preached. So the fact that he did not look so good after being stoned to death the day before does not mean he was suffering from some sort of sickness.
Acts 14:8 And there sat a certain man at Lystra, impotent in his feet, being a cripple from his mother’s womb, who never had walked:
Acts 14:19 And there came thither certain Jews from Antioch and Iconium, who persuaded the people, and, having stoned Paul, drew him out of the city, supposing he had been dead.
Acts 14:20 Howbeit, as the disciples stood round about him, he rose up, and came into the city: and the next day he departed with Barnabas to Derbe.
Acts 14:21 And when they had preached the gospel to that city, and had taught many, they returned again to Lystra, and to Iconium, and Antioch,
In writing this though there was something that had not sunk in before and that is once Paul was finished teaching on Derbe he went back to where they had almost ended his teaching career once and for all. Even the threat of death did not deter Paul.
