Why did Jesus say it's hard for Saul to "kick against the goads"?
Stubborn animals kick against the goads (a goad is a long rod with a sharp
end that is used to prick an animal to move or to move in a different
direction). Kicking against the goads inflicts pain to the kicker. Jesus was saying that in the process of
persecuting Christians, Saul was hurting himself. Since he
wasn't hurting himself physically, the Lord was likely referring to the impact on Saul's conscience.
How did persecuting Christians hurt Saul's conscience?
Instead of behaving like criminals, the Christians he arrested, imprisoned and
killed most likely exuded
grace, confidence and forgiveness. Stephen's words and demeanor as he
was martyred (see
Stephen stoned) also may have stayed with Saul, who may have even tried to
overcome the effect on his conscience by persecuting more vehemently -
kicking against the goads - which aggravated the self-inflicted pain.
Why did they fall "to the ground" (Acts 26:14) in the
first place?
See
Saul on the road to Damascus.
Why isn't Acts 26:16-18 found in Acts 9:6 (see
Road to Damascus)?
To use his trial 'defense' to instead preach the Gospel to his pagan Roman
audience, Paul is condensing above what Jesus revealed to him since his
conversion about the commission for his life, as well as the Gospel.
Whose "power" (Acts 26:18) is Paul telling his audience that they are under?
"Satan" (Acts 26:18) for everyone who hasn't been converted.
What must they do?
"Turn ... to God, that they may receive forgiveness of
sins and an inheritance among those who are sanctified by
faith in" (Acts 26:18) Jesus.
