Sword of the Spirit

For this book, the title has come from a combination. The sword, according to Paul, being of the Spirit, and the Word of God as it says in Ephesians 6:17. And Jesus, the Son of God, is that Word, as said in John 1:1. Jesus, by his own statement, said, "He that hath no sword, let him sell his garment, and buy one ... It is enough" (Luke 22:36 and 38). Thus, the sword of Jesus Christ.
