The Overlords are explicitly depicted as devils. Why would Clarke do this? What other religious imagery can you see in the novel, and what purpose does this imagery serve?

The Overlords as well as their self-sacrificing mission was for the better humanity. Through the novel, the Overlords are represented as administrators of British colonial, but they are idealized representations. Just once, humanity admits the rule of Overlords as being a usual part of their lives, the Overlords expose their heretofore concealed. The Overlords were not all-powerful. Actually, they envy from human beings and occur in a tragic state of their individual, as their job was to organize the human race for evolution and not to change themselves. Overlords were not rather as compliant and complaisant as they appeared to be. Overlords themselves were unable to seam the Over mind, but assisted it to bridge species, developing other races' by ultimate union with it. Now, basically the Overlord is telling about that religion is just the name of natural phenomena of science that has yet to be developed; the impression in that time and with further investigation. All the things we consider religion will eventually move into the category of those things. It is in the history to prove and back this up as well. For example, persons use to ponder will o' the wisps were haunting spirits on the swamps of Ireland and Britain, but several people now consider that  this all was just the natural gases result. So, religion converts science as there is an increase in our information. Then all over again, plenty of mystery is left by the novel toward the end, and it was may be signifying that there will constantly be a mystical or religious sideways to mortality and after it science will always be chasing it in one way or the other (Clarke)
