In Word-Faith theology, rhema is said to be the "spoken Word of God," while logos is considered the "written Word of God." This doctrine is used to support extra-Biblical revelation, such as "words of knowledge" or "prophecies."

Proponents assert that rhema is the Greek word used in the Sword of the Spirit passage:

> "...the sword of the Spirit, which is the word of God" (Ephesians 6:17)

Therefore, they claim we use the Sword of the Spirit by standing in faith on the specific word God has given us for our particular situation and confessing it.

There is nothing in the text to suggest that the sword of the Spirit is associated with continued, personal revelation. Commentators note that rhema is generally interchangeable with logos. The likely reason for the use of rhema here is that the vast majority of Paul's audience was illiterate; thus, the hearing and transmission of the Gospel was primarily by spoken means. There is no indication that rhema implies a special communication from which we receive private, personal messages.
