Who is the fountain opened for?

The fountain opened for sin and uncleanness is not universally extended to all individuals without distinction, but is specifically designated for God's elect, as indicated in Zechariah 13:1 where it mentions the house of David and the inhabitants of Jerusalem. This signifies that the salvation offered through the fountain is tailored for those whom God has chosen and redeemed. It emphasizes the doctrine of particular redemption within sovereign grace theology, which asserts that Christ's atoning work effectively secures salvation for His chosen people, thus ensuring that the fountain is a means of grace that leads to eternal life for those designed by God in His covenant.
