He is best known for his book "The Lord Our Shepherd" (). This is an exposition of Psalm 23, originally given to the Evangelical Movement of Wales in 1979.

Psalm 103 Psalm 103 is the basis of several hymns. A paraphrase of Psalm 103 in German is "Nun lob, mein Seel, den Herren", written by Johann Gramann in 1525, which was translated by Catherine Winkworth as "My Soul, now Praise thy Maker!" and published in 1863. English hymns include "Praise, my soul, the King of Heaven", written in the nineteenth century by Henry Francis Lyte, and "Sing to the Lord and praise him". In the 16th century, Claudin de Sermisy set the psalm. The song "Bless The Lord" in the musical "Godspell" is based on this psalm. Psalm 103 Psalm 103
