John 135 The next day again John was standing with two of his disciples, 36 and he looked at Jesus as he walked by and said, “Behold, the Lamb of God!” 37 The two disciples heard him say this, and they followed Jesus. 38 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?” 39 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. 40 One of the two who heard John speak and followed Jesus was Andrew, Simon Peter’s brother. 41 He first found his own brother Simon and said to him, “We have found the Messiah” (which means Christ). 42 He brought him to Jesus. Jesus looked at him and said, “You are Simon the son of John. You shall be called Cephas” (which means Peter).

When John identified Jesus as the Lamb of God, he connected Jesus with the entire Old Testament, which explains in detail the need for a sacrifice to remove sin and to fix all things. John made it personal. Standing before them was the One who was the fulfillment of all their dreams and greatest needs.
The immediate response was to follow Jesus and learn of Him. This is also our choice–between each of us alone and our Creator, Savior God. Will we follow Him? Learn from Him? Notice in verse 42 how those who make a decision to follow Jesus are forever changed.
