"Every word of God is pure; He is a shield to those who put their trust in Him." - Proverbs 30:5

"as newborn babes desire the pure milk of the word, that you may grow thereby, if indeed you have tasted that the Lord is gracious." -  1 Peter 2:2,3

There is power in the word of God and just like food nourishes our body, the word of God nourishes our soul and mind. Equip yourself with the word of God and use it in your defense against the wiles of the devil.
Praise the Lord!
