Here's an example of a Lutheran hymn on the theme of justification. Note how it expresses a complete idea without an over-reliance on external context.

"Lord, 'Tis Not that I did Choose Thee" by Josiah Conder, 1789-1855
Lord, 'tis not that I did choose Thee;
That, I know, could never be;
For this heart would still refuse Thee
Had Thy grace not chosen me.
Thou hast from the sin that stained me
Washed and cleansed and set me free
And unto this end ordained me,
That I ever live to Thee.
'Twas Thy grace in Christ that called me,
Taught my darkened heart and mind;
Else the world had yet enthralled me,
To Thy heavenly glories blind.
Now my heart owns none above Thee;
For Thy grace alone I thirst,
Knowing well that, if I love Thee,
Thou, O Lord, didst love me first.
Praise the God of all creation;
Praise the Father's boundless love.
Praise the Lamb, our Expiation,
Priest and King enthroned above.
Praise the Spirit of salvation,
Him by whom our spirits live.
To the great Jehovah give.
