We can only imagine the training John put into these two men that caused them to immediately leave John, their teacher, and follow Jesus. There was no jealousy with John (see also 4:1-2). His ministry was driven by the knowledge that Jesus was the Messiah and must be followed because of what the prophets told of him. Even when these two were challenged by Jesus, “What are you seeking?” they did not hesitate to request going with Him to the place where He was staying. “He said to them, “Come and you will see”” (1:38-39).
I believe without a shadow of a doubt that the first responsibility of a disciple-maker is developing in disciples a passionate desire to walk close with the Lord. This is the core ingredient of a disciple. Without this there will be little gained in the discipling process. The presence of Christ and His glory, transforms by the power of the Spirit (2 Corinthians 3:17-18). Are you discipling, and is this essential element first in your training?
