"Lord, if it's you," Peter replied, "tell me to come to you on the water." "Come,"he said. Then Peter got down out of the boat, walked on the water and came towards to Jesus. But when he saw the wind, he was afraid and, beginning to sink, cried out,"Lord, save me!" Immediately Jesus reached out his hand and caught him. "You of little faith," he said "why did you doubt ?"

This is how the birth of Jesus Christ came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be with child trough the Holy Spirit. Because Joseph her husband was a righteous man and did not want to expose her to public disgrace, he had in mind to divorce her quietly.
But after he had considered this, an angel of the Lord appeared to him in a dream and said, "Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins."
All this took place to fulfil what the Lord had said through the prophed: "The virgin will be with child and will give birth to a son, and they will cal him Immanuel"- which means, "God with us."

After they had heard the king, they went on their way, and the star they had seen in the east went ahead of them until it stopped over the place where the child was.
