"The Walking Father in Heaven" is about putting earthly reality into religion. The deception in religion is not that it is focused on overcoming death, but that it pretends to know what it does not. We do not know what happens when we die. We only know that we will die. "Walking Father" points to a discipline of human salvation that is at least authentic. Jesus said "a disciple in the kingdom of heaven is like the owner of a house who brings out of his storeroom new treasures as well as old."
Along those lines, "Walking Father" is contemporary and timeless.
