The Báb was a Prophet of God. He was sent by God to teach us how to live, and so, He was perfect. Are we perfect? We all know that children and even moms and dads are not perfect and we sometimes make mistakes. God sent us the Báb and Bahá'u'lláh so that we could learn to be better and better. Here is an example of one such case:
One time, God showed a man named 'Ali Khan a miracle. A miracle is something very wonderful that happens, but we can't understand how it happens. This miracle proved to ‘Ali Khan that the Báb was God's Prophet. This was a sign of God's love for 'Ali Khan.
At this time the Báb was in a terrible prison up in the mountains far from His home. His warden, the man who takes care of the prison, was this 'Ali Khan. He wouldn't let anyone come and see the Báb. This was a sad thing because so many people loved the Báb and they couldn't speak to Him or know if He was well. The Báb had only His secretary with Him, who would write down the Báb's precious Words as He spoke, and the secretary's brother who would buy things in the town.
There was a man who, because he loved the Báb very much, was called a Bábí. This man had traveled a long way just to see the Báb, but when he got to the town near the prison the warden wouldn't let him see the Báb. Not only that, he wouldn't let him sleep in the town. But this Bábí wouldn't give up. He wanted to see the Báb so much he stayed by the town and slept outside the gates.
The Báb knew about this Bábí. One day He told His secretary that the next day this Bábí would come into the prison to see them. His secretary was very surprised. How could he come into the prison? The warden wouldn't let anyone come in to see them!
