One of the two which heard John speak, and followed him, was Andrew, Simon Peters brother (John 1:40).
Andrew is almost the forgotten disciple. He was not, like Peter, James, and John, part of the inner circle of disciples. Yet, Andrew had an outstanding characteristic. He was always bringing people to Christ.
The first person he introduced to Jesus was his brother, Peter. He first findeth his own brother Simon, and saith unto him, we have found the Messiah, which is, being interpreted, the Christ. And he brought him to Jesus (John 1:41,42). Earlier, Andrew had heard Jesus speak and immediately followed Him (v.37). Andrew became one of the first soul winners.
The next time we see Andrew is in connection with the feeding of the five thousand. He is the one who told the Lord, There is a lad here, which hath five barley loaves, and two small fishes (John 6:9). Our Lord honored the faithfulness of Andrew and the willingness of the lad and performed a mighty miracle.
The third reference to Andrew in Johns gospel is in chapter 8. And there were certain Greeks among them that came up to worship at the feast: the same came therefore to Philip, which was of Bethsaida of Galilee, and desired him, saying, Sir, we would see Jesus. Philip cometh to Andrew: and again Andrew and Philip tell Jesus (John 12:2022). Andrew is still attempting to bring people to Jesus.
The last reference to Andrew in the New Testament is in the book of Acts after the Lords ascension from the Mount of Olives. And when they were come in, they went up into an upper room, where abode both Peter, and James, and John, and Andrew. . . . These all continued with one accord in prayer and supplication (Acts 1:13,14). Ten days later the power of the Holy Spirit came upon him, enabling him to continue to bring people to Jesus for the rest of his life. NPS
