Peter is an example of Christ's power to save us in spite of our fears and failures, because God has given us our faith, by the power of the Holy Ghost, and Christ prays for our faith to be upheld and strengthened. At his powerful sermon preached at Pentecost, Peter was bold in the Holy Ghost, and confronted the enemies of Christ, called them out for their sin in murdering Jesus, and commanded them to repent of their sin and have them washed away by the blood of Christ's sacrifice for sinners. Not only were believers strengthened and encouraged by the manifest demonstration of the power of the Spirit, but thousands of lost souls fled to Christ for forgiveness and salvation that very day! Peter testified to the glorious ministry of Jesus, and how the evil men in his audience had murdered Him by wicked hands. This was carried out in accordance with God's foreknowledge and determined counsel. Yet they were all still guilty of regicide and deicide. This was a bold accusation of criminal conduct of the worst kind! No longer was Peter afraid of these wicked people, but stood up to them and held nothing back of the truth. This sermon by Peter brought extreme fear and conviction in the hearts of many of his listeners: men and brethren, what shall we do, they cried out. This gave Peter his entrée to declare salvation and forgiveness of sin by the Lord Jesus! Repent and be baptized for the remission of sin! Soon after this, Peter and John healed a lame man at the temple gate by the power of the Lord Jesus. Peter then launched into the praises of Christ, how that the God of Israel had glorified His Son Jesus, the very same person Whom they had delivered up to Pilate.
