Changed by the Resurrection

At that, Peter and the other disciple went out, heading for the tomb. The two were running together, but the other disciple outran Peter and got to the tomb first. Stooping down, he saw the linen cloths lying there, yet he did not go in. Then, following him, Simon Peter came also. He entered the tomb and saw the linen cloths lying there. The wrapping that had been on His head was not lying with the linen cloths but was folded up in a separate place by itself. The other disciple, who had reached the tomb first, then entered the tomb, saw, and believed. For they still did not understand the Scripture that He must rise from the dead.

What did the resurrection of Jesus mean to Peter? According to John, when he and Peter saw the empty tomb, they still did not understand it.

After the Spirit of Jesus filled His followers on Pentecost, many things changed. For Peter, it meant changes in his understanding of spiritual things. It meant greater faith, stronger character, greater expectation of miracles. Many of the teachings Jesus had shared with His disciples as parables began to be understood.

What is different about us because of the resurrection of Jesus and His baptism of us in His Spirit?
