I am a huge fan of Henry van Dyke. Van Dyke was a remarkable man of many gifts. He was not only a minister, but also an ambassador (Netherlands during WW1), author (75 books), poet and naturalist. He wrote the popular hymn "Joyful, joyful we adore Thee" to the tune of Beethoven's Ode to Joy. He even officiated at the funeral of Mark Twain. He is also a Pennsylvania boy, born in Germantown.
I love his devotional writing because it is full of grace and incorporates many images from nature. The Upward Path is a daily devotional compiling many short excerpts from his writings. I also love Who owns the Mountains, which celebrates the joys of God's creation in longer entries.
Here is an excerpt from The Upward Path: "A silent love is acceptable only from the lower animals. God has given us speech that we should call upon His name. Worship is to religion what fragrance is to the flower."
