Chapter three- specifically; the story where Peter restores the lame man's ability to walk. I don't know about anyone else, but I squealed like a nerd getting a sneak peek at the newest Star Trek movie when Peter did that. And to think- this was the same man who denied and abandoned his Savior and best friend a month and a half before.
Kinda leaves one in awe of God, huh?
"But Peter said, 'I do not possess silver and gold, but what I do have I give to you: In the name of Jesus Christ the Nazarene--walk!'
And seizing him by the right hand, he raised him up; and immediately his feet and his ankles were strengthened."
