Acts 2.14-36

Peter's sermon in Acts 2:14-36 tells how God authenticated Jesus as both Lord and Christ. Peter stands up and proclaims that what the crowd was observing was a fulfillment of Joel's prophecy concerning the last days. Now that Peter and the others had been baptized and filled with the Spirit they discovered that being Spirit-empowered could overcome their natural limitations and frailties...they were no longer timid and afraid, but filled with the Spirit they were bold and confident.
