“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” (John 1:40–42a). There was an instinctive reaction in Andrew’s soul that caused him to tell someone else what he had encountered.
Andrew had just been standing with John the Baptist listening to what he said about Jesus and immediately followed Him. This meeting with the Son of God was so powerful that he was compelled to get his brother Peter. It is obvious that Andrew’s personal witness was enough for his brother to drop what he was doing and come see the Messiah for himself. It is the beginning of a new life for Peter especially, that would “turn the world upside down” (Acts 17:6). What a spontaneous impact these men made.
No budgets, no costly enterprises, no evangelism classes, and no external prompting apart from the work of God by the Holy Spirit. It was simply spontaneous evangelism – telling others what God has done in transforming your life and what you have seen. We can do the same through a personal walk with the Savior!!
