How do we know that Jesus is the fountain for our sins?

The identification of Jesus as the fountain for our sins is rooted in biblical prophecy and His sacrificial role. In Zechariah 13:1, it is proclaimed that a fountain shall be opened, and the New Testament affirms this by revealing Jesus as the Fulfillment of these scriptures. John the Baptist called Him the 'Lamb of God who takes away the sin of the world' (John 1:29), affirming that Jesus is the means by which God offers reconciliation. Additionally, Scripture emphasizes that all who come to Him will find forgiveness, showing that the fountain remains open to all who seek His grace, reinforcing that He is the only way to avoid the wrath of God due to sin.
