5 On the next day, their rulers and elders and scribes were gathered together in Jerusalem; 6 and Annas the high priest was there, and Caiaphas and John and Alexander, and all who were of high- priestly descent. 7 When they had placed them in the center, they began to inquire, “By what power, or in what name, have you done this?” 8 Then Peter, filled with the Holy Spirit, said to them, “ Rulers and elders of the people, 9 if we are on trial today for a benefit done to a sick man, as to how this man has been made well, 10 let it be known to all of you and to all the people of Israel, that by the name of Jesus Christ the Nazarene, whom you crucified, whom God raised from the dead— by this name this man stands here before you in good health. 11 He is the stone which was rejected by you, the builders, but which became the chief corner stone. 12 And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved
(Acts 4:5-12 NASB)
All the big-wigs get together for the trial of Peter and his colleagues. But what are they on trial for? Attacking someone? Stealing something? No, they are on trial for healing someone of a lifelong problem! Can you believe that? Peter has called on Jesus Christ to help this man who has been suffering all of his life, a man that everyone knew of and could do nothing for, and all they can do is throw those who helped him and put him on trial.
But there is more to it than just that, it wasn’t healing so much as the Name by which that healing came – the Name of Jesus Christ. This is the real reason for the trial. So, the question is asked, and Peter boldly responds testifying of Jesus Christ whom those very same people had executed. He testified that though they had reject Jesus He had risen above them and was now the cornerstone one which everything relies, and that salvation can only come through Him.
Readiness to testify, boldness to testify. Only by being filled with the Holy Spirit is this readiness and boldness possible. We must be continually immersed in Him, the Holy Spirit, 24/7, every day of every year that we live on this Earth.
