“And take the helmet of salvation, and the sword of the Spirit, which is the word of God” Ephesians 6:17.
Helmet of salvation protects your head and your thinking. We are given a promise that we shall be saved and this protects our hope about the future. We can feel safe, because we are going to our eternal home and stay with our heavenly Father forever.
The sword is the weapon of offense. We attack our enemy with it. It pierces darkness, brings light and freedom to the captives and also shows the path we have to go.
