Joh 1:32 - 36 "And John bore witness: "I saw the Spirit descend from heaven like a dove, and it remained on him. I myself did not know him, but he who sent me to baptize with water said to me, 'He on whom you see the Spirit descend and remain, this is he who baptizes with the Holy Spirit.' And I have seen and have borne witness that this is the Son of God." The next day again John was standing with two of his disciples, and he looked at Jesus as he walked by and said, "Behold, the Lamb of God!" 

John bore witness to the reality of Jesus' deity. Jesus was recognized as the Messiah, one sent from God, one who was God. He was Yahweh, He gives the Holy Spirit for the Holy Spirit proceeds from Him and The Father. He was the sent Lamb of God, the only one who could take away sin. 

John's disciples saw and heard and they began to follow Jesus. Their hearts were prepared they knew of their need for repentance. They wanted to be near Jesus, to be with Him. They also recognized the glory of Jesus and they told their friends and relatives of who they had come to know. One of them Andrew was the brother of Simon. Jesus gave Simon a new name Peter, the "rock" was what Jesus named him. 

Joh 1:37 -42  "The two disciples heard him say this, and they followed Jesus. Jesus turned and saw them following and said to them, "What are you seeking?" And they said to him, "Rabbi" (which means Teacher), "where are you staying?"  He said to them, "Come and you will see." So they came and saw where he was staying, and they stayed with him that day, for it was about the tenth hour. One of the two who heard John speak and followed Jesus was Andrew, Simon Peter's brother. He first found his own brother Simon and said to him, "We have found the Messiah" (which means Christ).  He brought him to Jesus. Jesus looked at him and said, "So you are Simon the son of John? You shall be called Cephas" (which means Peter)." 

Jesus went into Galilee, region where He grew up as a boy. He found Phillip and called Him to be part of His learners group as a Rabbi. Philip told his freinds and neighbors that he had met and wanted to follow Jesus. He knew Jesus to be the promised one from Moses, the sacrificial Lamb of the Law and the revelation of what the Prophets too Israel had talked about. This man, Jesus, whose adoptive father was Joseph of Nazareth. He was more than a man, He was the fulfillment that all men are looking for as a redeemer to save them from sin. 

Joh 1:43 - 45 "The next day Jesus decided to go to Galilee. He found Philip and said to him, "Follow me."  Now Philip was from Bethsaida, the city of Andrew and Peter. Philip found Nathanael and said to him, "We have found him of whom Moses in the Law and also the prophets wrote, Jesus of Nazareth, the son of Joseph." 

Philip told Nathanael and Nathanael couldn't believe that someone from Nazareth could have that kind of influence and power. Jesus told Natanael where and exactly when he located him. Jesus Natanael then knew was no ordinary man, Jesus was God's only begotten Son, the true King of Israel. The Lord of Lords and King of Kings. Jesus the mman was the ruler of the universe come as a man. 
Jesus promised you will see a lot of great things, greater than being able to see you even when you are not with me. 

Joh 1:46 -50  "Nathanael said to him, "Can anything good come out of Nazareth?" Philip said to him, "Come and see." Jesus saw Nathanael coming toward him and said of him, "Behold, an Israelite indeed, in whom there is no deceit!"  Nathanael said to him, "How do you know me?" Jesus answered him, "Before Philip called you, when you were under the fig tree, I saw you."  Nathanael answered him, "Rabbi, you are the Son of God! You are the King of Israel!" Jesus answered him, "Because I said to you, 'I saw you under the fig tree,' do you believe? You will see greater things than these." 

Jesus said you will see heaven opened. I have power over heaven and earth. The angels are at my command. They minister to me and are my messengers. They come and leave at my command. 

Joh 1:51  "And he said to him, "Truly, truly, I say to you, you will see heaven opened, and the angels of God ascending and descending on the Son of Man."
