Definition: The term "armchair" originally referred to a comfortable, sitting position, but its meaning has evolved into a phrase used for couches or other furniture that are made from a material resembling human skin. In the Bible, "armchair" refers to someone who is not fully conversant with their religious beliefs and practices. The idea of being able to sit comfortably in one's home without knowing what to do with it has been likened by scholars as an analogy for understanding God’s will through faith alone (Isaiah 65:1-8).
