40 Andrew, Simon Peter's brother, was one of the two who heard John's witness and followed Jesus. 41 The first thing he did after finding where Jesus lived was find his own brother, Simon, telling him, "We've found the Messiah" (that is, "Christ"). 42 He immediately led him to Jesus. Jesus took one look up and said, "You're John's son, Simon? From now on your name is Cephas" (or Peter, which means "Rock").

Commentary on John 1:37-42
(Read John 1:37-42)
The strongest and most prevailing argument with an awakened soul to follow Christ, is, that it is he only who takes away sin. Whatever communion there is between our souls and Christ, it is he who begins the discourse. He asked, What seek ye? The question Jesus put to them, we should all put to ourselves when we begin to follow Him, What do we design and desire? In following Christ, do we seek the favour of God and eternal life? He invites them to come without delay. Now is the accepted time, 2 Corinthians 6:2. It is good for us to be where Christ is, wherever it be. We ought to labour for the spiritual welfare of those related to us, and seek to bring them to Him. Those who come to Christ, must come with a fixed resolution to be firm and constant to him, like a stone, solid and stedfast; and it is by his grace that they are so.
