St. John did so by Baptizing people.
John the Baptist saw Jesus become the Messiah, and he also bears witness to the spirit of a dove. John the Baptist also baptized Jesus.
Because St. John was Filled with the Holy Spirit.
John the Baptist was the "voice in the wilderness" that spoke of the coming messiah. John asked people to repent and baptized people in the Jordan river. When Jesus came to him, John told his followers to follow him instead. John said "he must increase and I must decrease". John was an apostle of Jesus who traditionally wrote the Book of John (Fourth Gospel). John was the brother of James, known as the sons of Zebedee and also Sons of Thunder because they had tempers. John writes of John the Baptist in the Gospel starting with John 1:6.
John the baptist was his cousin. Although there was an other John people think he is the cousin of Jesus but he was not, but he was a deciple.
Jesus never said anything but god spoke in the orm of he spirit a dove.
Because he baptised Jesus.
No. John the baptist came before Jesus, calling people to repent because some one greater (Jesus) was coming. The promised advocate was the Holy Spirit. Joh 14:26 The Helper, the Holy Spirit, whom the Father will send in my name, will teach you everything and make you remember all that I have told you.
He baptized into water, but the one coming after him (Jesus) would baptize into the Holy Spirit.
By revealing to him that his cousin, the Lord Jesus, Is the Christ.
Hard to say for sure who the first one was. John the Baptist, Jesus' cousin, was preaching and baptising 'in the wilderness' when Jesus came to him and asked him to baptise him in the name of the holy spirit.
John the Baptist (who was actually a second cousin of Jesus') was beheaded.
John the baptist then they are cousins.
