Unless Someone Is Born Again

Who: One of the cool things about going to the Seminary is their library, which has a book called "Hymns and Poems" by Emanuel Cronenwett, who was a somewhat early Lutheran (1841-1931) of the Ohio Synod, which is now a part of the ELCA. There are many translations and many originals in this book, including the following.
Changes: I've updated the text a little.
Note: Since the hymn ends at an odd place, one might want to close with stanza 2 of LSB 601. Here I give, as the last stanza, the original (uncopyrighted) translation by George A.T. Rygh of Kingo's famous hymn.
Tune: The meter is 87 87 887, and I propose "Es ist das Heil" as the melody, which is found in LSB 601.

Unless someone is born again

Of water and the Spirit,

They cannot- being dead in sin-

The kingdom, life inherit;

But God be praised, for thus says Christ,

"All who believe and are baptized-

Shall of a certainty be saved."

Here water and the Word are joined,

As means, command, and promise;

Conditioned by the outward sign,

The Spirit comes upon us.

Our body with the wash is laved,

While faith believes the might that saves,

And trusts the Lord's assurance.

It is not simply water, then,

With which we are anointed,

But water with His Word- Amen!-

By Triune God appointed.

The Word makes this a quick'ning flood,

And adds the grace of Jesus' blood,

Which kills and yet enlivens us.

This water is a means of grace,

A giving of salvation,

An earnest of the Father's face,

Bent kindly on all nations;

For all a cleansing pool, in truth, 

The fount of everlasting youth,

Of which are born God's children.

Rich, golden, costly font of life,

Pure grace pour from our Savior,

Blest covenant with healing rife,

Seal of the Father's favor;

In you our sins are washed away,

And we, enrobed in Jesus, may

With glee await His coming.

(With one accord, O God, we pray:

Grant us Thy Holy Spirit;

Look Thou on our infirmity

Through Jesus’ blood and merit.

Grant us to grow in grace each day

That by this sacrament we

Eternal life inherit.)
