(John 1:29-34) So, John didn’t know Jesus really, other than what God had revealed to him. However, the key things that God revealed to him was how he would recognize who Jesus was. We see here that Jesus came to John to be baptized. Even though, as far as John was concerned, he wasn’t worthy to baptize Jesus that is what Jesus required of him. He did this and then John saw first hand the Holy Spirit come down onto Jesus, and this was exactly what God had told John would happen. At that point John had no doubt at all that this was Jesus. He told everyone what he had been told and experienced.
