Some of those who listened to the apostles had taken an active part in the condemnation and death of Christ. Their voices had mingled with the rabble in calling for His crucifixion. When Jesus and Barabbas stood before them in the judgment hall and Pilate asked, “Whom will ye that I release unto you?” they had shouted, “Not this Man, but Barabbas!” Matthew 27:17; John 18:40. When Pilate delivered Christ to them, saying, “Take ye Him, and crucify Him: for I find no fault in Him;” “I am innocent of the blood of this just Person,” they had cried, “His blood be on us, and on our children.” John 19:6; Matthew 27:24, 25. – {AA 42.3}
Now they heard the disciples declaring that it was the Son of God who had been crucified. Priests and rulers trembled. Conviction and anguish seized the people. “ They were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?” Among those who listened to the disciples were devout Jews, who were sincere in their belief. The power that accompanied the words of the speaker convinced them that Jesus was indeed the Messiah. – {AA 43.1}
“ Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.” – {AA 43.2}
Peter urged home upon the convicted people the fact that they had rejected Christ because they had been deceived by priests and rulers; and that if they continued to look to these men for counsel, and waited for them to acknowledge Christ before they dared to do so, they would never accept Him. These powerful men, though making a profession of godliness, were ambitious for earthly riches and glory. They were not willing to come to Christ to receive light. – {AA 43.3}
Under the influence of this heavenly illumination the scriptures that Christ had explained to the disciples stood out before them with the luster of perfect truth. The veil that had prevented them from seeing to the end of that which had been abolished, was now removed, and they comprehended with perfect clearness the object of Christ’s mission and the nature of His kingdom. They could speak with power of the Saviour; and as they unfolded to their hearers the plan of salvation, many were convicted and convinced. The traditions and superstitions inculcated by the priests were swept away from their minds, and the teachings of the Saviour were accepted. – {AA 44.1}
