Acts 4:5-8 - By what power did you do this?

4:5-7

So Peter and John were held in prison overnight, and then in the morning the various panjandrums got together to interrogate Peter and John. Annas was the high priest, and Caiaphas had previously been the high priest, and so was still influential. Their basic question was “by what power or what name did you do this?” It is interesting that at this point they refer to what they have done, rather than what they preached.

4:8

Several weeks earlier when questioned by a servant girl Peter denied Jesus, now questioned by those in authority he answers clearly and boldly. Peter was a changed man. Peter was “filled with the Holy Spirit”. It is the Holy Spirit who changes us, and without Him we can do nothing. Here Peter is addressing the leaders of the people.
