Again, the next day, John stood with two of his disciples. And looking at Jesus as He walked, he said, "Behold the Lamb of God!" The two disciples heard him speak, and they followed Jesus (John 1:35-37).
When John opened his mouth about Jesus, two people who heard him speak followed the Lord. We must open our mouths about the Lamb of God if we want people to follow Him.
Look what happens next in John 1:40-42,
One of the two who heard John speak, and followed Him, was Andrew, Simon Peter's brother. He first found his own brother Simon, and said to him, "We have found the Messiah" (which is translated, the Christ). And he brought him to Jesus.
We have a chain reaction happening here. John says, "Behold the Lamb of God," and two men follow Jesus. One of the men, Andrew, goes straight to his brother and brings him to Jesus. It is interesting to note that it says he "first" found his own brother—indicating that Simon was not the only one that Andrew found and brought to the Lord.
The remainder of this chapter in John tells us how Philip told Nathaniel about Jesus and was able to persuade him to meet the Lord with the words "come and see."
These stories from the first chapter of John reveal to us what we should be doing once we meet Jesus. We need to bring our friends and loved ones to the Lord. We should be inviting them to "come and see."
Take a moment right now and ask God to show you someone who you should talk to about Jesus. Then get busy and do it. You just may see a chain reaction of salvations.
