What is the difference between the “sword of the Spirit” (Eph. 6:17) and Christ’s sword mentioned in Revelation 2:12, 16; 19:11-16? What is the difference in meaning between the Greek words, “logos” and “rhema” as they relate to the Word of God? Which word is used to describe the “sword of the Spirit”? How is the Word of God practically used like a sword?
