I greet Thee, who my sure Redeemer art,The Presbyterian Hymnal (1990) has this as hymn 457, and employs all verses unaltered.
My only trust and Savior of my heart,
Who pain didst undergo for my poor sake;
I pray Thee from our hearts all cares to take.
Thou art the King of mercy and of grace,
Reigning omnipotent in every place;
So come, O King, and our whole being sway;
Shine on us with the light of Thy pure day.
Thou art the life, by which alone we live,
And all our substance and our strength receive;
Sustain us by Thy faith and by Thy power,
And give us strength in every trying hour.
Thou hast the true and perfect gentleness,
No harshness hast Thou and no bitterness;
O grant to us the grace we find in Thee,
That we may dwell in perfect unity.
Our hope is in no other save in Thee;
Our faith is built upon Thy promise free;
Lord, give us peace, and make us calm and sure,
That in Thy strength we evermore endure.
(words from The Cyber Hymnal)
Paul enjoined the Ephesians to "5:19 Speak to one another with psalms, hymns and spiritual songs. Sing and make music in your heart to the Lord, 20 always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ."
Among the uses to which hymns are put is instruction in faith and theology. I Greet Thee, Who My Sure Redeemer Art is not only a hymn of praise, but a hymn that provides us with instruction that is squarely rooted in the Reformation.
