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. MacMillan drew on his 12 years of experience as a shepherd to argue that the shepherd theme pervades the entire psalm. MacMillan wrote a number of other books including "Wrestling with God" () consisting of addresses on the life of Jacob given to the Evangelical Movement of Wales
Psalm 110 Psalm 110 Psalm 110 is the 110th psalm of the Book of Psalms, generally known in English by its first verse, in the King James Version, "The said unto my Lord".
