Peter was not content to merely know what he had seen. He repeatedly refers to other witnesses. He reviewed the testimony of the Old Testament. He was determined to not only know that Jesus rose, but to strengthen his conviction with proof after proof.  Let us not be content with knowing that Jesus rose, or hearing about it once or twice. Instead let’s intentionally strengthen our conviction. How? By examining all the witnesses in scripture we can find. By talking about Jesus’ resurrection with fellow Christians. That is how the Holy Spirit works. That is how conviction grows stronger.
