All Christian soldiers need the same rigid training to know how to properly handle the Sword of the Spirit, “which is the word of God.” The sword that Paul refers to here is the Holy Scriptures.
Ang lahat ng Kristiyanong sundalo ay nangangailangan ng gayunding mahigpit na pagsasanay upang matutuhang gamitin ng tama ang tabak ng Espiritu, na "walang iba kundi ang Salita ng Diyos."
