When Peter proclaimed Jesus as the only way after the healing of the lame man, the religious leaders had a real problem.  Continuing in verse 13, the leaders noted the boldness of Peter and John.  Jesus had been crucified to stop His message,yet here were these two men declaring not only did He still live, but that He was still working miracles.  For the Saducees, who proclaimed there was no resurrection after death, this was a real problem.  Today, as we exhibit the power of the resurrection of Christ, we present a problem to the world.  We need to proclaim Jesus Christ as the Savior of the world, but more importantly we need to exhibit Him as Savior by our actions.  If we are hated and persecuted, we don't need to pray for God's vengeance on our enemies but for their salvation.  As His followers, we must be willing to live by His example and love those who hate us, all the way to the cross.  As were Peter and John, we may be called ignorant and unlearned, but we need to leave them marveling because they know we have been with Jesus.  The world may hate us, but we can never hate the people of the world.  If we as Jesus' followers are filled with hate for non Christians, then we can never expect them to marvel at Jesus.
