Peter was the front of a new movement. The Holy Spirit had used him to lead three thousand people to Jesus for salvation. The man was making Jesus known to the world and in the process Peter’s name was being spread too. 
But Peter was only consumed with continuing to draw closer to God. He was actually heading to the temple to pray when he stopped to do the work of the Lord and to glorify Jesus. He and John met with a beggar outside the temple. Peter told the man “Silver and gold have I none; but such as I have I give thee: In the name of Jesus Christ of Nazareth rise up and walk.”
His statement, which was basically “I don’t have what you’re after, but I have Jesus, let me share him with you”, should be an example of what our continued mindset should be: I’m content as long as I have Jesus and no matter what’s going on around me -good or bad- I am going to focus on who I am in Christ.
