John the Baptist was the one calling out to the people of Jerusalem and Judea to repent, turn from their sins, and be baptized before the coming of the Messiah.
It was he who performed the baptism of Jesus Christ. As Jesus came up out of the water, heaven opened, and the Spirit of God,
like a dove, descended upon him.
Witnesses to the baptism heard a voice from heaven saying, "This is my son, whom I love; with him I am well.
Witnesses to the baptism heard a voice from heaven saying, "This is my son, whom I love; with him I am well.
The baptism of Jesus Christ mark the beginning of his ministry on earth.
Mt 28:19 Go ye therefore and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit.
Acts 22:16 And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord.
Baptism is the washing away of sins but after the immersion in water, all must maintain a good conscience towards God.
1 Pet 3:21 The like figure to which, even baptism, doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience towards God,) by the resurrection of Jesus Christ:
A conscience void of offense towards God, and towards men is the baptism of Jesus.
Mk 10:38 But Jesus said to them, Ye know not what ye ask: can ye drink of the cup that I drink of? and be baptized with the baptism that I am baptized with?
Mk 10:39 And they said to him, We can. And Jesus said to them, Ye shall indeed drink of the cup that I drink of: and with the baptism that I am baptized with shalt ye be baptized;
The first baptism is the washing away of sins and the second baptism is the answer of a good conscience towards God as Jesus Christ did even up to his death in the cross. What I mean is, like Judas, not all baptized in water is save.
