Through water and the Spirit came God’s revelation; through Christ’s blood came our salvation. Christ’s ministry was possible through the former. Men’s redemption through the latter. God announced it through his prophets and the Spirit testified of it.
“This is the one who came through water and blood, Jesus Christ, not by water alone, but by the water and blood. The Spirit is the one who testifies, and the Spirit is truth. So there are three that testify, the Spirit, the water and the blood, and the three are of one accord” (1 JN 5:6-8).
Through Jesus’ baptism, God revealed his relationship with the Son and Spirit. This Trinitarian relationship gave Christ his strength and wisdom to minister and endure suffering. This same Trinity has been bestowed to us through baptism to live out our ministry and encounter tribulations.
Jesus’ obedience flamed his father’s love: “You are my beloved Son; with you I am well pleased” (MK 1:11). Our obedience, too, can lead us to fulfill our baptism “You will draw water joyfully from the springs of salvation” (IS 12:3) if we believe in Jesus as his father instructed us “Everyone who believes that Jesus is the Christ is begotten by God, and everyone who loves the Father loves also the one begotten by him” (1 JN 5:1).
All who are thirst for the LORD can come to the waters of baptism. (cf. IS 55:1)
