Verse 8
Then Peter, filled with the Holy Ghost - Which guided him into all truth, and raised him far above the fear of man; placing him in a widely different state of mind to that in which he was found when, in the hall of Caiaphas, he denied his Master, through fear of a servant girl. But now was fulfilled the promise of Christ, Mat 10:18-20; And ye shall be brought before governors and kings for my sake; but take no thought how or what ye shall speak; for it is not ye that speak, but the Spirit of your Father that speaketh in you.
