Ephesians 6:17 (KJV)
And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
The Roman soldier would be armed with a double edged short sword. His sword would be kept razor sharp always cleaned and ready for use at a moment’s notice.
The Christians soldiers’ sword is the sword of the spirit, the bible the very word of God. The only offensive weapon the Christian soldier has is his sword. The sword must always be kept at the ready. In order to keep his sword sharp the bible needs to read daily. Verses need to be memorized so they can be recalled as necessary when we are in combat with the forces of darkness.
Dear Lord: Give me the wisdom to understand your word. The only weapon I have to fight the prince of darkness. Help me to keep your words in my heart so I will always be ready for combat.
In Jesus name I pray amen.
