Online audio versions of George MacDonald's "Unspoken Sermons"
The theological heart of the nineteenth-century Christian author George MacDonald is found in his Unspoken Sermons. All thirty-six of these have now been recorded and made available online for free by David Baldwin. You can locate them here. David says, "Each sermon was carefully recorded using studio quality equipment with the end goal of helping others encounter MacDonald's thought in a fresh, new way or perhaps for the first time."
This is a really great resource and I intend to check out a few. David has suggested that a good place to start may be number 19 — "Abba, Father."
