I love Frederick Buechner and came across this wonderful piece of writing from his website www.frederickbuechner.com/content/imagination
Even a thousand miles inland you can smell the sea and hear the mewing of gulls if you give thought to it. You can see in your mind's eye the living faces of people long dead or hear in the mind's ear the United States Marine Band playing "The Stars and Stripes Forever." If you work at it, you can smell the smell of autumn leaves burning or taste a chocolate malted. You don't have to be asleep to dream dreams either. There are those who can come up with dramas laid twenty thousand leagues under the sea or take a little girl through a looking glass. Imagining is perhaps as close as humans get to creating something out of nothing the way God is said to. It is a power that to one degree or another everybody has or can develop, like whistling. Like muscles, it can be strengthened through practice and exercise. Keep at it until you can actually hear your grandfather's voice, for instance, or feel the rush of hot air when you open the 450-degree oven.
If imagination plays a major role in the creation of literature, it plays a major one also in the appreciation of it. It is essential to read imaginatively as well as to write imaginatively if you want to know what's really going on. A good novelist helps us do this by stimulating our imaginations—sensory detail is especially useful in this regard, such as the way characters look and dress, the sounds and smells of the places they live and so on—but then we have to do our part. It is especially important to do it in reading the Bible. Be the man who trips over a suitcase of hundred-dollar bills buried in the field he's plowing if you want to know what the Kingdom of Heaven is all about (Matthew 13:44). Listen to Jesus saying, "Come unto me, all ye that labor and are heavy laden, and I will give you rest" (Matthew 11:28) until you can hear him, if you want to know what faith is all about.
If you want to know what loving your neighbors is all about, look at them with more than just your eyes. The bag lady settling down for the night on the hot-air grating. The two children chirping like birds in the branches of a tree. The bride as she walks down the aisle on her father's arm. The old man staring into space in the nursing-home TV room. Try to know them for who they are inside their skins. Hear not just the words they speak, but the words they do not speak. Feel what it's like to be who they are—chirping like a bird because for the moment you are a bird, trying not to wobble as you move slowly into the future with all eyes upon you.
When Jesus said, "All ye that labor and are heavy laden," he was seeing the rich as well as the poor, the lucky as well as the unlucky, the idle as well as the industrious. He was seeing the bride on her wedding day. He was seeing the old man in front of the TV. He was seeing all of us. The highest work of the imagination is to have eyes like that.
