Jesus said to her, “Everyone who drinks of this water will be thirsty again, but whoever drinks of the water that I will give him will never be thirsty again. The water that I will give him will become in him a spring of water welling up to eternal life.” The woman said to him, “Sir, give me this water …”
— John 4:13-15, ESV.
The water that wells up to eternal life is baptism. Baptism is living water made alive by the word of God. And through this water Christ grants his eternal life and righteousness to all who believe.
One of the first celebrations of Epiphany is of the Baptism of Jesus in the Jordan River.
In order to fulfill all righteousness, he took our place. He submitted to John’s baptism in the Jordan river. John’s baptism was for repentance, and in this way Jesus took our sin, and identified completely with us sinners. He began his ministry by taking our place, and becoming our substitute. He became the Lamb of God. (Genesis 2:8).
When we were baptized, the water washed our sins away. When Jesus was baptized, he accepted our sins from the water as his own. John said, “Behold, the Lamb of God, who takes away the sin of the world!” (John 1:29, ESV).
To Jordan’s river came our Lord,
The Christ, whom heavenly hosts adored,
The God from God, The Light from Light,
The Lord of glory, power, and might.
The Savior came to be baptized
The Son of God in flesh disguised
To stand beneath the Father’s will
And all His righteousness fulfill.
Then from God’s throne with thunderous sound
Came God’s own voice with words profound:
“This is My Son,” was His decree,
“The one I love, who pleases Me.”
The Father’s word, the Spirit’s flight
Anointed Christ in glorious sight
As God’s own choice, from Adam’s fall
To save the world and free us all.
— “To Jordan’s River Came Our Lord,” LSB 405:1-2, 4-5.
