What was Saul doing when Stephen was stoned?
At the time of Stephen's stoning, Saul was at the height of his persecution against Jewish believers. He had brought about Stephen's death, actively opposing those Jewish believers. This occurred before Saul's conversion on the road to Damascus the following year.
Les explains that there was a seven-year interval between Pentecost and the stoning of Stephen, placing it around 36 A.D. At that time Saul was at the height of his persecution of Jewish believers and had brought about Stephen's stoning. The next year, Saul was converted on the road to Damascus. This timeline shows that events in Acts were not compressed into a single year but unfolded over time.
